Shop Safety Rules

Your workshop is only as safe as you make it. Take responsibility for the safety of those who use or visit it. This list of rules is by no means complete, so remember that common sense is a must.

Smithy strongly discourages the use of casters or wheels on metal-working machine benches. The weight of the machine could result in the bench tipping while being moved. Once the machine is mounted, consider your workbench to be permanent. If you must move the machine, first remove it from the bench

1. Read this manual thoroughly before operating your machine. Don’t try to do more than you or your machine can handle. Understand the hazards of operating a machine tool. I

n particular

, remember never to change speeds or setups until the machine

is completely stopped and nev

er operate it without first rolling up your sleeves.

2. Wear proper clothing. Avoid loose-fi

tting clothes, gloves, neckties, or jewelry that could get caught in moving parts. If you have long hair, tie it up or otherwise keep it from getting into the machine. Always wear non-slip footwear.

3. Protect yourself. Use ANSI approved safety glasses, goggles, or a face shield at all times. Use safety glasses designed for machinery operation; regular glasses will not do. Have extras available for visitors. Know when to wear a face mask or earplugs as well.

Keep your work area clean and organized.

Clut

tered work areas and benches

invite accidents. Have a place for everything and put everything in its place.

5. Childproof your work area and keep children away from the machine while it is in use. Childproof your shop with padlocks, master switches, and starter keys or

stor

e the machine wher

e chi

ldr

en do not ha

ve access to it.

6. Never operate your machine under the influence of drugs and alcohol.

7. Keep track of tools. Remove adjusting keys and wrenches from the machine before

operating. A chuck key or misplaced Allen wrench can be a safety hazard.

Avoid accidental starts. Turn the switch to the

OFF posi

tion before plugging in the

machine. Turn the speed dial to zero before starting your machine.

9. Ground your machine. The machine has a three-conductor cord and three-prong, gr

ounding-t

ype plug. Nev

er connect the power supply without proper grounding

10. Keep your mind on your work. By paying attention to what you are doing and avoiding distractions you will spend many safe, enjoyable hours in your workshop.

11. Never leave your machine running unattended.

WARNING

Machine Safety Rules

1. Stop the machine before servicing. Stop the machine before making changes, removing debris, or measuring your work.

2. Don’t over reach. Don’t reach over the machine when it’s operating. Keep your hands out of the way.

3. Turn the switch OFF. Turn the switch to off before plugging in the machine. Turn the speed dial to zero before starting your machine.

4. Use proper tooling. Use only recommended accessories and understand how they should be used before trying them out. Don’t try to make a tool into something it isn’t or attempt to use a tool in inappropriate ways. Remember to always use the proper tooling for the material you are cutting. Reference a general machining guide such as Machinist Ready Reference for recommended tooling for your material.

Secure your work.

Before starting y

our machine, be certain that your workpiece is

properly and securely mounted. Flying metal is dangerous!

6. Do not run you machine beyond its limits of travel. Befor

e starting your

oject, ensure that your work area does not go beyond the limits of travel on your machine. Going beyond the limits of travel will cause serious damage to your machine which wi

ll not be covered by your warranty.

7. Run your machine at recommended spindle speeds and feed rates. Always cut at the r

ecommended speed and feed rates for the type of metal that you are cutting for optimum performance. Do not begin your cut until the machine has reached the full and proper speed.

Do not change the direction of the spindle rotation or leadscrew rotation

while your machine is running.

Changing the rotation direction of the spindle or

leadscrew while your machine is running could cause serious damage to your machine.

9. Do not stop the spindle by hand. Always use your on/off switch to stop the spindle from rotating.

10. Do not clear chips by hand. Metal chips are very sharp and can easily cut your hand. Use a brush to clear chips.

11. Protect bed ways. When removing or installing tooling from your lathe spindle, place a piece of wood or other material across the bed to protect the ways from being damaged if the tooling is dropped.

12.

Keep your machine maintained.

Millhead Components & Functions

The photos below show the front and back of the millhead of the Smithy Granite machine. The millhead holds the tooling necessary to perform milling and drilling operations. The following section identifies the components and functions of the millhead.

A. Spindle Cover - The spindle cover protects the spindle from dust and debris. It also protects the operator from injury. The spindle cover should be in place whenever the machine is in operation. The drawbar is located under the spindle cover.

B. Millhead Cover - The Mi

lhead co

er pr

otects the belt and pulleys of the millhead.

The co

er should always be in place when the machine is in operation.

C. Quill Lock - The quill lock locks the mill/drill quill in place during a horizontal milling operation or while changing tools.

D. Mill/Drill Spindle - The mi

l dri

l spindle is an R-8 taper. It holds and rotates the the

tool

ing used during milling and drilling operation. The spindle also moves in and out of

the millhead quill. The quill is an internal part which is not seen in this picture.

E. Drill Press Handles - The drill press handles move the quill in and out of the mill head during a dri

ing operation. Rotating the handles in a clockwise direction moves the

qui

l downward, out of the millhead casting.

F. Coarse Feed/Fine Feed Clutch - Pulling out the coarse feed/fine feed clutch knob engages the drill press handles/coarse feed. Pressing the knob in engages drill/mill fine feed hand wheel. To easily engage/disengage the clutch, rotate the drill press handles slight

L-10. Leadscrew Clutch- Is designed to slip to reduce damage to the machine apron if the carriage is accidentally run into the head of the machine.

Carriage Assembly

The carriage assembly consists of:

• Crossslide table

• Carriage; the lower portion of the table that rides on the bed ways,

• Apron; the portion that hangs from the cross-slide table in front of the machine.

The carriage moves by hand or by power along the bed ways. Its function is to support the cutting tool rigidly while in the lathe mode and to secure the workpiece while in the mill mode. The carriage can be locked into place with the lock found on the back of the carriage.

The figure to the above right identifies and defines the major components of the carriage assembly.

A. Cross-SlideTable - The top portion of the carriage assembly. It supports the compound angle toolpost (not pictured) which holds the lathe cutters and tooling. The table also supports y

our workpiece when oper

ating the mill. The cross-slide table has four,

7/16” sized t-slots for securing tooling and mounting workpieces.

! NOTICE !

There is a neutral position with this selector. Be sure that it is completey engaged in either the metric or inch mode before you begin your threading operation.

B. Cross-Slide Handwheel - This handwheel moves the table toward and away from the operator along the Y-Axis. Rotating the handwheel clockwise moves the table away from the operator while moving it counterclockwise moves the table toward the operator.

C. Longitudinal Handwheel - This handwheel is located at the bottom left of the carriage assembly. Manually rotating the handwheel clockwise will move the carriage assembly along the X-Axis towards the tailstock end of the machine. Rotating the handwheel counter clockwise will move the the carriage assembly towards the headstock end of the machine.One revolution moves the assembly approximately .040”.

NOTE:

This handwheel is for coarse movements only. Use the handwheel at the end of

the leadscrew for fine movement (0.001”)

D. Half-Nut Engagement Lever - This lever closes the half-nut on to the leadscrew. When the half-nut is engaged, in the down position, the table assembly will be powered to move right and left along the X-Axis leadscrew.

E. Longitudinal and Lateral Powerfeed Selector - This selector determines whether the carriage will be power

ed to move along the X-Axis (longitudinal axis) or the Y-Axis (lateral axis). When the lever is in the upper position the table will move along the Y-Axis. When moved into the lower position, the table will move along the X-Axis. Center posi

tion is neutral.

F. Threading Dial - The threading dial is used to coor

dinate consecutive cuts when

cut

ting threads. Restarting each cut from the same point on the dial ensures that each

cut follows the same path, leading to accurately machined threads.

G. Saddle - The saddle supports the cr

oss-sl

ide table and mo

es along the X

Axis of the

machine.

H. Apron - The apron houses the gear mechanism for the X and Y-Axis powerfeed.

! NOTICE !

The hal

f-nut engagement lever is only engaged for rapid

travel or threading operations.

Overview

The Quick-Start Manual you received before delivery of your Smithy machine provides detailed instructions for mounting and locating your machine. Please complete those instructions if you have not already done so. As you unpack, it is a good idea to inventory the parts. (See chapter 3 for a complete list.) Before operating your machine, you should assemble the remaining components of your machine, clean the machine, and lubricate it. This section will guide you through those steps.

Assembly of Minor Components

The installation of the drill chuck, arbor and arbor plug; mill spindle covers; and several handles should be completed according to the procedures described below.

Drill Chuck and Arbor

Before proceeding both the arbor and the chuck should be thoroughly cleaned to ensure a good fit. Once cleaned attach the chucks to the respective arbors. Follow the steps below to achieve the best possible fit.

Step 1: Place the arbor in a f

reezer for about 1 hour to slightly shrink the metal.

Step 2: Remove the cold arbor from the freezer and place it into the drill chuck.

Step 3: Use a soft mallet or a block of wood to tap the end of the arbor.

Step 4: Allow the arbor to return to room temperature.

Handles

Install any handles or handwheels that have been removed for shipping. Handles can be hand installed and tightened with a flat-head screwdriver. Remove and reverse the tailstock handwheel.

Cleaning & Lubricating Your Machine

Smithy machines are shipped with a light protective grease coating that must be removed prior to use. Use a noncorrosive kerosene or white mineral spirits to remove the coating. WD-40® also works well.

Once cleaned, your Smithy must be lubricated. Make sure to lubricate carefully and thoroughly before starting the machine. Use a pump oil can and a supply of good qual

ity SAE30 weight nondetergent oil or 30-weight compressor oil. Lubricants can be obtained at most home and building supply stores. A lubrication point chart can be found on the backside of the millhead.

Lubrication Schedule

Lubrication depends a lot on the use of your machine and your climate. The schedule below is intended to be used as a guide, use your best judgement for lubricating your machine based on your use and environment.

Check Oil Before each use Oil Ports Before each use Add Oil As Needed

See Chapter 11 for a complete maintenance schedule.

Adjusting Backlash

Backlash is lost motion in the screw. The user will notice an initial small movement in the handwheel before the screw responds. The procedures in this section will help minimize backlash.

Adjusting Backlash from the Cross-Slide Screw

Before making any adjustments to the cross-feed screw system, all the gibs on the table and carriage system should be checked and adjusted as described previously.

Excessive backlash in the cross-slide can come from three different places.

• The fit of the cross-slide screw to the front screw mount

• The fit of the cross-slide screw into the brass crossfeed nut

• The fit of the br

ass cross-feed nut into the carriage casting

There are adjustments for each of these areas. Follow the procedures below to make each adjustment.

Adjusting Backlash Cross-Slide Screw to the Front Screw Mount

Step 1: Loosen the two nuts that hold the cross-slide handwheel on to the end of the cross-slide screw.

Step 2: Tighten the inner nut slowly whi

le checking the ease of movement of the cross-slide handwheel. When the screw starts to become difficult to turn, loosen the nut slightly so that the screw turns freely.

Step 3: Hold the inner nut in place with a wrench and tighten the outer nut against the inner nut to lock both nuts in position.

Step 4: Recheck the backlash.

Cross-Slide Screw to Brass Nut & Nut to Saddle

If there is still excess backlash after the previous adjustment, the backlash is either between the cross-slide screw and the brass nut or between the brass nut and the saddle. The following procedure covers both adjustments.

Step 1: Remove the rear support on the backside of the cross-slide table.

Step 2: Loosen the allen bolt that locks the brass nut into the saddle. (See Figure 5.23)

Step 3: Use the handwheel to mo

ve the cross-slide table toward the operator side of the machine. Watch under the table from the backside and stop before the cross-slide scr

ew comes out of the brass nut.

Step 4: Slowly tighten the four adjusting screws on the brass nut, one at a time, until a sl

ight drag is felt while turning the cross-slide handwheel. It is best to continue turning the handwheel back and forth while adjusting the nut to balance ease of operation and backlash.

Step 5: Reinstall the rear support and tighten the locking bolt for the brass nut.

Step 6: Recheck the backlash on the cross-slide.

Adjusting Backlash from the Longitudinal Leadscrew

Excessive backlash in the longitudinal feed can come from two places.

• The fit of the longitudinal feed screw to the right-hand mounting trestle

• The fit of the half-nut to the feed screw

Engage the half-nut lever. Slowly turn the longitudinal handwheel clockwise as viewed from the right end of the machine and watch the gap between the dial and the feed screw mounting trestle. Reverse the direction you are turning the feed screw and see if the gap increases slightly. If so then there is some backlash in the mounting. Follow the procedure below to reduce the backlash.

Adjusting the fit of the longitudinal feed screw to the right-hand mounting trestle

Step 1: Remove the retaining screw and washer in the right end of the longitudinal feed handwheel.

! NOTICE !

If you find that the four adjusting screws will not stay in place, use a small amount of thread-locking compound to keep the screws tight. If you use a Lock-Tite® product, use the Lock-Tite® Purple, not Red which will not allow for future adjustments

Step 2: Unscrew the handwheel from the end of the feed screw.

Step 3: Using a punch and a small hammer, tighten the spanner nut about one-eighth

of a turn and recheck the backlash in the leadscrew.

Step 4: If backlash is acceptable, replace the handwheel, washer, and retaining screw. If more adjustment is needed, repeat step 3 above.

Half-Nut to Leadscrew Backlash

Worn threads on the half-nut can cause excessive backlash in the longitudinal direction. Half nuts are made of a brass-like material and do wear out over a period of time. The only fix for a worn half nut is to replace the worn nut with a new one.

Adjusting Mill Feed Backlash

Excessive backlash in the vertical fine feed can come from two places.

• The fit between the worm gear and the pinion gear shaft

• The fit of the quill gear to the quill rack

Adjusting the Fit Between the Worm Gear and Pinion Gear Shaft

ollow the procedure below to adjust the fit between the worm gear and pinion gear.

Step 1: Remove the fine-feed handwheel and dial.

Step 2: Loosen the two setscrews that hold the left and right worm gear bearing sup-

ports in place. They are located on top of the vertical feed housing at the left and right end of the worm gear.

! NOTICE !

The longitudinal handwheel (R

ack & Pinion) is intended for rapid, coarse feed and is not calibrated for fine measurement. There is no backlash procedure for this mechanism.

! NOTICE !

The bearing housing has two holes in the outside surface to allow a punch or spanner wrench to turn the housing.

Step 3: Use a small spanner wrench or a punch with a small mallet to rotate the bearing supports one at a time. The support bearings ar

e mounted slightly of

f center in these housings and rotation of the housings will raise or lower the worm gear down towards the pinion gear. The bearing support on the right should be rotated clockwise and the left should be rotated counter clockwise. Rotating the right and left bearing supports should be done in conjunction with each other.

Step 4: Turn the right housing and watch the worm gear shaft to see in which direction it moves. Turn the housing in the direction that will move the worm gear down towards the pinion gear.

Step 5: Move to the left housing and repeat step 4.

Step 6: Alternate moving the front a little and then the rear a little while turning the

worm gear to check for binding.

Step 7: Stop as soon as resistance is felt in the rotation of the worm gear. The adjustment is completed.

Step 8: Tighten the setscrews to the bearing housings to lock adjustment in place.

Adjusting the fit of the Quill Gear to the Quill Rack

Adjusting the fit between the quill shaft feed gear and the quill rack is done using the split section of the feed gear. The feed gear is made up of two parts.

• A wide section that is locked to the feed shaft by a key and has a fixed position on the shaft

• Another section that is not as wide and is not keyed to the shaft. It is held in place on the shaft via a locking nut and can be repositioned as desired.

The narrow section can be offset from the wide section to give the effect of a gear with thicker teeth. This in turn will give a tighter tooth-to-tooth fit between the feed shaft gear and the rack on the spindle.

Adjustments are made on the split gear from up inside the mill head casting. This is accessible from under the mill head between the quill and the support column. Follow the procedure below to make these adjustments.

Step 1: Look into the millhead casting and locate the items shown in the drawing 5.26.

Step 2: Turn the feed shaft with the coarse feed handwheel until the locking tab of the

locking washer is accessible. Lock the quill in that position with the quill lock lever on the rear of the millhead.

Step 3: Bend the locking tab straight and use a small punch to loosen the spanner nut just enough to be able to rotate the adjustable gear with the same punch and small hammer.

Step 4: With the quill still locked in position, have someone turn the coarse feed handwheel clockwise unti

l it remo

ves any backlash. Then have them

hold the handle

in this position until the completion of step 6

. This will move the bottom part of the

wide fixed gear to the left as viewed from below.

Step 5: Using the punch and small hammer, tap the narrow movable gear toward the right. This wi

Step 7: With the quill still locked, move the coarse feed handle and check for a reduction in backlash.

Step 8: Bend the locking tab back into one of the slots in the spanner nut.

Adjusting Drive Belt Tension

Adjust the belt tension before using your machine and recheck it periodically.

Adjusting Millhead Belt Tension

Step 1: Remove the millhead cover.

Step 2: Position the roller to the outside of the belt.

Step 3: Loosen the shaft with a wr

ench on the two flats at the

top of the shaft.

Step 4: Position the roller against the flat side of the belt and apply light thumb pressure to tension the belt.

Step 5: Tighten the roller shaft.

Adjusting Lathe Belt Tension

The lathe-belt tensioner is made up of a Quick Release Handle and the Tension Adjustment Knobs. Raise the Quick Release Handle to apply tension and down to release tension. Proper setting of the tension follows:

Step 1: Raise Quick Release Tension handle all the way up

Step 2: Adjust the tension by turning the knurled knob clockwise to increase tension or

counter clockwise to loosen tension. Once the belt tension is adjusted the Quick Release Handle can be used to r

elease and apply tension f

or positioning belts.

Overview

This section contains information on installing tooling for your lathe and mill.

Setting-up Lathe Tooling

Ther

e are three main areas to set-up tooling when you are using the lathe

portion of your Granite 1300 series tool:

•Lathe Spindle

•Compound Angle Toolpost

•T

lstock

Lathe Spindle

Any tooling that is mounted to the lathe spindle will use the D1-4 camlock mounting system.

Thr

ee studs on each at

tachment ar

e inserted into matching holes in the lathe

spindle. (S

ee figur

socket on the spindle flange and rotate each camlock clockwise to the locked position. The indicator hashmark on each camlock socket should be somewhere between the 5 and 6 o’clock position.

If the desired rotation on any cam lock cannot be obtained, the mounting studs may need to be adjusted. (See Troubleshooting in chapter 12.)

Tailstock

The tailstock will accept any tooling with a Morse Taper #3 shank or arbor. This type of mount is a friction-fit taper, so it is important that the mounting surfaces be clean and dry. You will need to extend the tailstock barrel approximately 1/2 to 3/4 inches before inserting any tooling, and then firm hand pressure is all that is needed to lock tooling into the taper.

Installing Compound Angle Toolpost

The compound-

angle toolpost (CA

TP) is mounted to the top of the cr

oss-sl

ide table using 10mm t-bolts, washers and nuts. You can substitute t-nuts and the proper length studs in place of the t-bolts if desired. Mount the toolpost on the table surface wherever there is a t-slot that allows the tooling to reach your workpiece.

Installing Tooling into the Compound Angle Toolpost

The four-sided turret can hold up to four individual cutters up to a 1/2 inch in siz

e. T

o insert tool

ing, loosen the screws on top of the turret with the provided wrench. Insert tooling and tighen the screws again. Each cutter can be moved into place by loosening the top turret lock and rotating the turret counter clockwise 90º. Each cutter in the turret must be adjusted so that the cutting tip is aligned with the center line of the workpiece. This is achieved by installing shims or f

eeler gauges under the cut

ter bef

e tightening it in place.

! NOTICE !

You can use either the tang or drawbar style arbors, however, it is important that the thr

eaded drawbar hole be plugged with a bolt or setscrew before inserting into the barrel so that the item will be automatically ejected when you retract the barrel.

Setting-up Tooling in the Mill/Drill Spindle

This section will explain tool mounting in the mill/drill spindle.

The mill spindle of the Granite 1300 series machines is an R-8 (Bridgeport®) standard. It features a straight shank with a flared nose for centering the tool and a keyway for alignment.

Aligning Tooling

Use the pr

ocedure below to align y

our tooling in the R-8 spindle:

Step 1: Select the appropriate tool or fixture.

Step 2: Wipe the surfaces of the tooling and spindle interior to ensure a

proper fit. Grease or debris on either surface will cause misalignment.

Step 3: Align the keyway in your tooling with the key inside the mill spindle and insert the fixture in the lower mill spindle opening.

You can feel the key in the mill spindle with your finger. It is located just beyond the tapered portion of the spindle.

Securing R-8 Tooling with the Drawbar

Use the pr

ocedur

e below for the drawbar:

Step 1: Remove the mill spindle cap located on the top of the mill belt cover and insert a drawbar (SAE standard 7/16-20) from the top of the spindle.

Step 2: Tighten the dr

wbar clockwise into the fixture or tooling that is inserted into the mill spindle opening. Use the spanner wrench to stabilize the spindle while tightening the drawbar.

Step 3: Use a wrench to apply torque to the drawbar. This will draw the fixture firmly into the spindle.

Step 4: Reinstall the spindle cap when the fixture/tooling is in place.

Removing R-8 Tooling from the Drawbar

Use the pr

ocedur

e below to r

emo

ve tooling using the drawbar method:

Step 1: Stabilize the drawbar with the spanner wrench and use a wrench to apply f

ce counter

clockwise to the dr

wbar nut.

Step 2: Loosen the drawbar two to three turns counterclockwise.

Step 3: Use a deadblow or brass hammer to strike a downward blow on the

top of the dr

wbar to loosen the fixtur

e f

om the spindle.

Unscrew the drawbar only two to three turns before striking. Unscrewing it further before striking the drawbar can damage the threads on the drawbar or the fixture.

Step 4: Continue turning the dr

wbar unti

l i

t unscrews from the tooling.

Step 5: After the tool is free from the spindle, hold the fixture with your free hand or use a catch box to prevent the tooling from dropping onto your machine or workpiece.

Figure 6.5 Use the supplied spanner wrench to hold

the spindle in place while tightening the drawbar

! NOTICE !

When instal

ling or removing tooling with sharp edges, always cover the sharp edges with a shop towel or appropriate covers or guards to prevent injuries. Always shield yourself appropriately when using hammers.

Overview

Before using the more advance features of your Granite 1300 Series Lathe-MillDrill, it is important to have a basic understanding of feeds and speeds. This section contains information on how to set the speed and feeds rates for your machine. We encourage you to learn and understand as much as you can about this fundamental element of machining. A general reference guide such as the Home Machinist Handbook or the Ready Reference are good reference guides to assist you with this task. As always, remember to follow the general safely rules listed below and in Chapter 2 of this manual.

Speed and Feed Rates Defined

Speed is how fast the spindle rotates. Feed rate is how fast the cutter moves along the workpiece.

Speed and f

eed r

ates ar

e calculated based on the t

ype of material y

ou are cutting, the size of the material and the type of cutter being used. Refer to the Home Machinist Handbook

(Item # 10-005) or Ready Reference (Item #10-015) for more detail. Remember, speed and feed rates are given in a range and you will need to adjust within that range for your machine’s size and power.

Speeds and Feeds

For your own safety and the safety of those around you, follow the rules below.

Never lea

ve or walk a

way from an operating machine.

Do not change motor rotation direction until the motor and spindle are fully stopped. Changing directions while the motor is running can damage the motor.

Setting the Spindle Rotational Speed

Once you have determined the proper speed and feed rate for the material that you are cutting and the type of cutter that you will be using, you will need to setup your machine to cut within the range of the selected speeds and feed rates.

Setting the spindle speed is a two-stage operation consisting of an initial belt position setting and a final adjustment with the variable speed selector on the front of the gearbox.

The drive system on your machine is much like a car with a manual transmission. It has a “transmission” with several gear ranges and a “throttle” to vary the speeds within each gear selection.

The belt positions give you three speed ranges and the electronic control gives fine adjustments within the selected range. The variable speed selector dial shows the speeds for each of the three speed ranges. These speeds are applicable to both the lathe and mill spindles.

Step 1: Refer to a machining reference guide such as the Home Machinist Handbook

Ready reference to determine the optimal rotational spindle speed

for the materials and tooling you are using.

Step 2: Examine the decal that surrounds the variable speed selector dial to determine which of the thr

ee bel

t posi

tions need to be selected inside of the

gearbox. The low

-speed range located on the inner ring of the dial (0-400 rpm) will require using the low-speed idler pulley and a dual-belt setup. The mid and high-speed ranges will use a single belt that bypasses the center idler pulley.

Figure 8.1 Use the Granite Speed Dial for fine adjustments

Low Range-Speed Set-up

For low-speeds (optional on early machines), you must convert to a double drive belt configuration. Use the procedure below to set up for low speed (400 RPM or less) operations.

Step 1: Release the belt tensioned at the motor by rotating the tension lever down.

Step 2: Remove the belt from the motor pulley by following steps 3-6 below.

Step 3: Loosen the cap screw on the shaft of the lathe/mill clutch inside the

pulley box and pull the selector lever outward to move the shifter fork arm away from the shi

fter fork.

Step 4: Slide the single belt off the spindle pulley and the end of the main driv

e spindle.

Step 5: Loosen the bolt that holds the gear quadrant and the reduction pulley br

acket in place. This will allow the two belts you are about to install to be

properly tensioned.

Step 6: Place the larger of the two belts on the smallest motor pulley sheave and on the largest pulley sheave of the speed reduction pulley. Place the smaller belt on the smallest sheave on the speed reduction pulley and the largest sheave on the main drive spindle pulley.

Below the gear formula is a repetition of the “Do not change selector handle positions while the machine is running” symbol.

The Header Row contains a number of symbols explained below:

This symbol refers to inch thread pitches (threads per inch). The “N” represents the distance the carriage assembly travels for each rotation of the spindle based on the positions of the selector lever (I-III) and selector lever 1-7. For example, if the distance traveled in one rotation of the spindle is 1/10 inch per rotation, the machine will travel 1 inch in 10 rotations, yielding 10 threads per inch (tpi).

This symbol represents the longitudinal (X-Axis Travel) in inches per spindle revolution.

This symbol represents the later

al Y-Axis T

ra vel) in

inches per spindle revolution.

This symbol refers to the the inch thread pitch. Inch pitches measures the distance between each thread peak.

Overview

This section of your manual covers threading operations on your Granite 1300 series lathe-mill-drill. This section will build the information presented in chapters 8 and 9. If you have not read these sections, please do so before continuing.

Leadscrew Safety Clutch Adjustment

Before begining your threading operation, note the leadscrew safety clutch may need to be adjusted.

The lead scr

ew saf

y clutch is f

unctioning in the thr

eading mode. It will slip to prevent damage to the machine apron if the carriage is accidentally run into the head of the machine.

NOTE:

The clutch will not prevent damage if the carriage or cross-slide table

pass the end of their mechanical limits

The clutch assembly is located inside the lathe pulley box. It is a round flat nub in the change gear shaft with the “D” gear. There are six setscrews above the springs and ball bearings located radially around the clutch in front of the gear. The setscrews screw inward toward the center of the clutch.

Threading

General Safety Operations

For y

our own safety and the safety of those around you, follow

the rules below and those listed in chapter 2 of this manual.

Never leave or walk away from an operating machine.

Do not change motor r

otation direction until the motor and spindle are fully stopped. Changing directions while the motor is running can damage the motor

If slippage occurs during your threading operation adjust the safety clutch by turning each setscrew one at a time a half turn each time untill the clutch is solid and no slippage occurs. Do not bottom the screws completely of the clucth will not work.

An approximate initial setting is when the set screws have two threads exposed from the surf

ace of the clutch housing.

Basic Threading

Refer to a machining reference guide such as the Machinist Ready Reference for threading theory and spindle speeds based on the material type and diameter that y

ou will be machining.

Step 1: Select the thread pitch which you want to cut from the chart located on the headstock of y

our Granite series machine (The is also reprinted on page 8-5 of this manual.) Chose the desired pitch from the chart and follow the horizontal row and vertical columns to set the correct positions for selector levers (1-7) and selector lever (I-III).

Step 2: Consul

t the thr

ead chart on the headstock support column f

or the

thr

ead pi

tch that you wish to cut. The bottom row of the chart will show you the gear set-up inside the pulley box that is required to cut the desired thread pitch.

Step 3: If changing the gear set-up is necessary to achieve the desired thread pitch, follow the procedure under the title “Changing Gears” in the next section.

Changing Gears

Step 1: The A gear is secured with a bolt and washer assembly and the location is fixed. To remove the gear remove the bolt and washer.

Step 2:The B and C gears share the same shaft and are secured with a snap ring. Remove the snap ring from the shaft to remove the gears.

Step 3: Place the proper gear in the A position for cutting the desired thread pitch. Reinstall the washer and bolt.

Step 4:The shaft for the B/C gears mounts on a slotted plate to adjust for the di

ent diameters of the gears. There are two flats on the end of the shaft to loosen and tighten the assembly to allow for adjustment. Adjust the B/C gear shaft as needed to accommodate the B and C gears needed for cutting your desir

ed thr

ead pi

tch.

Step 5: Loosen the hex head bolt. This allows the assembly to drop down.

Step 6: Position the installed B/C gear unit to mesh with the D gear.

Step 6: Rotate the gear assembly until the B gear meshes with the A gear.

Lock the assembly in place by tightening the hex head bolt.

The hex head bolt also tensions the speed reduction pulley support arm. Be sure the belts are in the appropriate position before tightening the hex head bolt.

Cutting Inch Threads

Step 1: S

elect the desired thread pitch that you wish to cut from the chart

located on the headstock of the Granite 1300 series lathe-mill-drill.

Step 2: Engage selector levers (1-7) and selector lever (I-III). Remember, you can use the jog knob located on the right side of the gear box to help align the gears if the levers are difficult to engage.

Step 3: Check the gear set

-up inside the pul

ley box to confirm the gearing is set-up correctly to cut your desired thread pitch. If the gears are not correct, change gears using the previous procedure.

NOTE:

The default factory setting is for cutting inch, SAE, threads.

Step 4: Confirm that your bel

ts inside the pulley box ar

e properly set-up to reach the recommended spindle speed for cutting your work piece material with your specific cutter.

Step 5: Set your compound angle toolpost to 29-1/2º and install the E8 carbide bit that came with your machine.

Step 6: I

nside the pul

ley box at the left lower side of the gear cluster is the

inch/metric lever

, which must be pushed away from you for inch threading.

Step 7: Tu rn y ou r m ac hi ne o n a nd ad j us t va ri ab le s peed to the reco mm ende d speed.

Step 8: Once you have made all of your tooling and machine settings, you are ready to begin the first pass. Set the dials on the compound angle toolpost and cross-slide table to zero. Move the compound angle toolpost into the desired position and feed the cutter into your workpiece using the small CATP feed handle. W

atch the thr

eading dial rotate until one of the numbers is just about to the reference mark. At this point apply firm constant downward pressure on the half-nut engagement lever until you feel the lever drop into position and the carriage begins to move. (More information to follow on the threading dial.)

Step 9: When you reach the end of the first cut, lift up on the half-nut engagement lever, back the cutter out using the CATP feed and return the cutter to the starting point.

Step 10: Feed the cutter in the desired amount for the next cut, wait for the same number as before to come up on the dial and engage the half nut. Continue making passes until you have completed the full depth of cut.

Using the Threading Dial to Cut Inch Threads

The threading dial is used for cutting inch threads only. Special procedures for cutting metric threads can be found in the section under “ Cutting Metric Threading” on the next page.

The thr

eading dial is a mechanical indicator f

or engaging the cut

ter at the exact same point for each consecutive pass. The numbers on the dial have no speci

fic reference to pitch, but they provide a reference point so you can start at the earliest available point and use the same number again for each consecutive pass.

Note:

When the carriage is mo

ving and the hal

f nut is engaged, you will notice

that the dial no longer rotates. This is normal.

Cutting Metric Threads

Step 1: Select the desired thread pitch that you wish to cut from the chart located on the headstock of the Granite 1300 series lathe-mill-drill.

Step 3: Check the gear set-up inside the pulley box to confirm the gearing is set-up correctly to cut your desired thread pitch. If the gears are not correct, change gears using the previous procedure.

Step 4: Confirm that your belt set-up inside the pulley box is properly set-up to reach the recommended spindle speed for cutting your work piece material with your specific cutting tool material.

Step 5: Set your compound angle toolpost to 29-1/2º and install the E8 carbide bi

t that came with your machine.

Step 6: Inside the pulley box at the left lower side of the gear cluster is the inch/metric lever, which must be pulled toward you for metric threading.

Step 7: Turn your machine on and adjust the variable speed to the recommended rpm.

Step 8: Once you have made all of your tooling and machine settings, you are ready to begin the first pass. Apply firm constant downward pressure on the hal

f-nut engagement lever until you feel the lever drop into position and the carriage begins to move. . Step 9: Do not disengage the half nut at the end of the pass, stop your machine and r

erse the f

eed dir

ection. Rotate the handle on the compound

angle toolpost counter clockwise to back out your cutter.

Step 10: Restart your machine and bring the cutter back to is original position. Stop your machine, reverse the direction again.

Motor

How to check a Motor

Get a car battery and attach the two wires coming from the motor to the terminals of the battery. If the motor runs, the motor is okay, if not it needs to be replaced.

Uncscrew brush caps and inspect the brush carbon, spring and wire. If damaged or worn out replace it.

Chuck and Accessories

If the chuck does not seat properly.

Adjusting the chuck mounting studs

The D1-4 mounting system used on all Granite machines consists of three adjustable studs mounted on the chuck and thr

ee rotating cam locks on the spindle flange. This is a very fast and accurate method of chuck mounting; however, there are some adjustments to be made to insure optimum fit and accuracy.

Removing the chuck

1. The first step in removing the chuck is to place a piece of wood on top of the machine bed underneath the chuck. This will protect the bed if the chuck accidentally slips out of your hand and falls onto the machine.

2. There is an alignment mark on each cam and on the spindle flange adjacent to each cam. Using the chuck key, turn the cam counter clockwise until the two marks align with each other as shown below.

3. Position all three cams in the unlocked position, put your right hand under the chuck for support and tap the chuck with a block of wood to break it loose from the spindle.

4. Inspect the mating surfaces on the end of the spindle and the back of the chuck for burrs or foreign matter. Clean and deburr these areas as necessary.

Installing and Adjusting the chuck

1. Make sure that the cams are aligned in the unlocked position and slide the chuck onto the spindle.

2. Turn each cam clockwise to lock the chuck in place.

3. Each cam should turn between 140o to 180oof a turn to lock correctly. See the diagram below.

4. If the cam turns less than one fourth of a turn, it will be necessary to remove the chuck and adjust the corr

esponding chuck stud.

5. Before removing the chuck, mark each location

on the chuck that will need

adjusting.

6. Remove the chuck and place it face down on a work surface.

7. There is a locking screw along side each chuck stud. Remove the locking screws for the studs that need adjusting.

8. Unscrew the studs one turn and install the locking screws.

9. Install the chuck and check the cam rotation. Repeat as necessary.

Since there are three studs and cam mounts on the chuck, there are three possible position that the chuck may be mounted. You will find that one of these positions will be slightly more accurate than the others. Try the chuck in all three possible positions. Once the most accurate position is determined, mark the chuck and spindle flange so that the chuck can be installed in the same position each time that it is mounted onto the machine. This is best done by putting a punch mark on the chuck and a corresponding mark on the spindle flange.

This next step is only for the 3-jaw self centering chuck.

Mark each of the three jaws, and the slot it is in. Remove the jaws, and keeping them in the same order, reinsert them into the next slot over making sure the scroll plate engages the first thread on the first jaw. Try the jaws in all three positions; one should be more accurate than the other two.

Leadscrew

Having trouble on the leadscrew backlash particularly on engaging the half nut?

Leadscrew Backlash Adjustment

Excessive backlash in the longitudinal feed can come from two places:

1. The fit of the longitudinal feed screw to the right hand mounting trestle.

2. The fi

t of the half nut to the feed screw.

Half nut to screw backlash

Worn threads on the half nut can cause ex

cessiv

e backlash in the longitudinal direction. Half nuts are made of brass and do wear out over a period of time. The only fix for a worn half nut is to replace the worn nut with a new one.

Crossfeed Backlash Adjustment

Excessive backlash in the crossfeed can be coming from three different places:

1. The fi

t of the crossfeed screw to the front screw mount.

2. The fit of the crossfeed screw into the brass crossfeed nut.

3. The fit of the brass crossfeed nut into the carriage casting.

There are adjustments for each of the above areas. Before making any adjustments to the cr

3. Hold the inner nut in place and tighten the outer nut against it to lock the nuts in position.

4. Recheck the backlash.

Crossfeed Screw to Brass Nut & Nut to Carriage (Locking Bolt)

If there is still an excess of backlash after the above adjustments are made, the play will be either between the crossfeed screw and the brass nut or between the brass nut and the carriage. The fol

1. Remove the crossfeed screw rear support.

2. Loosen the Allen head bolt that locks the brass nut into the carriage.

3. Crank the crossfeed table toward the operator side of the machine. Watch under the table from the backside and stop before the crossfeed screw comes out of the brass nut.

4. Slowly tighten the four adjusting screws on the brass nut, one at a time, until a slight drag is felt while turning the crossfeed handle.

5. Install the rear crossfeed support and tighten the locking bolt for the brass nut.

6. Recheck the backlash on the crossfeed.

If you find that the four adjusting screws are not staying in place, you can use a small amount of a thread-locking compound to keep the screws tight.

Granite Series Leadscrew Handwheel Fabrication & Installation (Earlier Machines)

Purchase part # G91027 or use the instructions below.

Installation of a handwheel to the right end of the leadscrew will allow a more precise lateral feeding of the carriage travel than is now possible using the carriage feed handwheel. The following is a simple handwheel plan that can be made using the Granite machine. The wheel portion can be made from a piece of mild steel, aluminum, or cast ir

on. The handle portion should be made of mild steel.

Hole is drilled & tapped to match the thread of the handle that was selected. The handle may be fabricated from scratch or purchased already made.

Screw the handwheel on the end of the leadscrew. Install a bolt & fender washer into the 5/16 x 24 hole that is in the end of the leadscrew to hold the handwheel in place. Screw the handle into the handwheel & tighten into place.

Note:

If you have an older Granite model, the end of the lead screw may not be drilled and tapped. This is a very simple process. You will need a 5/16 x 24 tap, a 17/64 or a “I” drill bit, and an electric hand drill. Set up your machine on the slow speed pulley, full RPM, with leadscrew turning counter clockwise as viewed from the right end and the gearbox set on 1 and “I”. By having the leadscrew turning as well as the drill, the drill bit will center itself and go straight down the center of the lead screw. Drill the hole about 5/8 inch deep. Tap the hole with the 5/16 tap. Do not forget to use oil when drilling and tapping.
