Page 12

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine for damaged, loose, or mis-adjusted parts—or any condition that could affect safe operation. Immediately repair/replace BEFORE operating machine. For your own safety, DO NOT operate machine with damaged parts!

MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab and pull the plug—NOT the cord. Pulling the cord may damage the wires inside. Do not handle cord/plug with wet hands. Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-9663.

Additional Safety for Bandsaws

Serious cuts, amputation, or death can occur from contact with the moving saw blade during operation or if blade breakage occurs. Serious injury or death can also occur from getting fingers, hair, or clothing entangled in moving parts if the machine is operated while the doors are open. To reduce this risk, anyone operating this machine MUST completely heed the hazards and warnings below.

HAND PLACEMENT. Placing hands or fingers

in line with blade during operation may result in serious injury if hands slip or workpiece moves unexpectedly. Do not position fingers or hands in line with blade, and never reach under table while blade is moving.

SMALL/NARROW WORKPIECES. If hands slip during a cut while holding small workpieces with fingers, serious personal injury could occur. Always support/feed small or narrow workpieces with push sticks, push blocks, jig, vise, clamping fixture.

BLADE SPEED. Cutting workpiece before blade is at full speed could cause blade to grab workpiece and pull hands into blade. Allow blade to reach full speed before starting cut. DO NOT start machine with workpiece contacting blade.

FEED RATE. To avoid risk of workpiece slipping and causing operator injury, always feed stock evenly and smoothly.

BLADE CONDITION. Dull blades require more effort to perform cut, increasing risk of accidents. Do not operate with dirt y, dull, cracked or badly worn blades. Inspect blades for cracks and missing teeth before each use. Always maintain proper blade tension and tracking while operating.

CLEARING JAMS AND CUTOFFS. Always stop bandsaw and disconnect power before clearing scrap pieces that get stuck between blade and table insert. Use brush or push stick, not hands, to clean chips/cutoff scraps from table.

BLADE CONTROL. To avoid risk of injury due to blade contact, always allow blade to stop on its own. DO NOT try to stop or slow blade with your hand or the workpiece.

GUARDS /COVERS. Blade guards and covers protect operator from moving bandsaw blade. The wheel covers protect operator from getting entangled with rotating wheels or other moving parts. ON LY operate bandsaw with blade guard in proper position and wheel covers completely closed.

BLADE REPLACEMENT. To avoid mishaps that could result in operator injury, make sure blade teeth face down toward table and blade is properly tensioned and tracked before operating.

UPPER BLADE GUIDE SUPPORT. To reduce exposure of operator to blade and provide maximum blade support while cutting, keep upper blade guides adjusted to just clear workpiece.

CUTTING TECHNIQUES. To avoid blade getting pulled off wheels or accidentally breaking and striking operator, always turn bandsaw OFF and wait for blade to come to a complete stop before backing workpiece out of blade. DO NOT back workpiece away from blade while bandsaw is running. DO NOT force or twist blade while cutting, especially when sawing small curves. This could result in blade damage or breakage.

WORKPIECE SUPPORT. To maintain maximum control and reduce risk of blade contact/breakage, always ensure adequate support of long/ large workpieces. Always keep workpiece flat and firm against table/fence when cutting to avoid loss of control. If necessary, use a jig or other workholding device.

WORKPIECE MATERIAL. This machine is intended for cutting natural and man-made wood products, and laminate covered wood products. This machine is NOT designed to cut metal, glass, stone, tile, etc.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage

not properly grounded

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Dust Collection

Adjustment

Overview

This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system.

2" Dust Port.......................................... 10 0 CF M

3" Dust Port.......................................... 250 CFM

4" Dust Port.......................................... 400 CFM

Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

The bandsaw is one of the most versatile woodworking machines. However, it has multiple components that must be properly adjusted for the best cutting results.

For practical and safety reasons, some adjustments and test operations must be performed before performing other necessary adjustments. Below is an overview of all the adjustments and the order in which they should be performed:

Initial Blade Tracking

"Tracking" refers to how the blade rides on the bandsaw wheels. Proper tracking is important for maintaining bandsaw adjustments, achieving correct blade tension, and cutting accurately. Improper tracking reduces cutting accuracy, causes excess vibrations, and places stress on the blade and other bandsaw components. The shape of the wheels and the orientation of the wheels in relation to each other determine how the blade tracks.

Bandsaw wheels are either flat or crowned and both shapes track differently. The G0948 has crowned wheels. As the wheels spin, a properly tracking blade naturally tracks at the center of the wheel (see

Figure 20).

using this machine BEFORE understanding its controls and related safety information. DO NOT operate, or allow others to operate, machine until the information is understood.

Model G0948 (Mfd. Since 08/21)

Page 25

DO NOT start machine until all preceding

setup instructions have been performed. Operating an improperly set up machine

may result in malfunction or unexpected results that can lead to serious injury, death, or machine/property damage.

To test run machine:

Tensioning Blade

A properly tensioned blade is essential for making accurate cuts, maximizing the blade life, and making other bandsaw adjustments. However, a properly tensioned blade will not compensate for cutting problems caused by excessive feed rate, hardness variations between workpieces, and improper blade selection.

1. Clear all setup tools away from machine.

2. Connect machine to power supply.

3. Turn machine ON, verify motor operation,

then turn machine OFF.

The motor should run smoothly and without

problems or unusual noises.

Remove key, as shown in Figure 23.

Optimal cutting results for any type of workpiece are achieved through a combination of correct blade selection, proper blade tension, properly adjusted blade guides and other bandsaw components, and using an appropriate feed rate.

Improper blade tension is unsafe, produces inaccurate and inconsistent results, and introduces unnecessary wear on bandsaw components. Over-tensioning the blade increases the chance of the blade breaking or wheel misalignment. Under-tensioned blades wander excessively while cutting and will not track properly during operation.

The method used to tension the blade is often a matter of preference. This manual describes two methods: the flutter method and the deflection method. Either method will help you properly tension the blade. Experience and personal preference will help you decide which method you prefer.

Figure 23. Removing key from ON/OFF paddle

switch.

5. Try to start machine with ON/OFF paddle

switch. The machine should not start.

— If the machine does not start, the switch is

working as designed.

— If the machine does start, immediately

stop the machine. The switch is not working correctly. This safety feature must work properly before proceeding with regular operations. Call Tech Support for help.

Note: Tensioning the blade before the Test Run was an approximate tension. The following procedures fine-tune the blade tension.

Model G0948 (Mfd. Since 08/21)

Page 26

The Flutter Method

Using the flutter method, you intentionally loosen the blade until it just passes the point of being too loose (when it begins to flutter). Then you gradually tighten the blade until proper tension is reached.

To tension bandsaw blade using flutter method.

1. DISCONNECT MACHINE FROM POWER!

Make sure blade is properly tracking as

Using blade tension adjustment knob, slowly

decrease blade tension until you see the blade start to flutter.

. Slowly increase tension until blade stops flut-

tering, then tighten blade tension adjustment knob an additional

⁄8 to 1⁄4 of a turn.

The Deflection Method

The deflection method is much more subjective than the flutter method. Each blade will deflect differently and every user will determine what "moderate pressure" means. The following are general guidelines for tensioning the blade with this method.

To tension bandsaw blade using deflection method:

1. DISCONNECT MACHINE FROM POWER!

Make sure blade is properly tracking as

2. instructed in Initial Blade Tracking on Page 20.

Raise guide post all the way and move upper

and lower guide bearings away from blade.

Rotate blade tension adjustment knob clock-

wise to apply tension to blade.

5. Using moderate pressure, push center of the blade sideways with one finger.

— If the blade deflects approximately 1⁄4", it is

properly tensioned. Proceed to

— If the blade deflects less than 1⁄4", it is over-

tensioned. Turn the blade tension adjustment knob counterclockwise two full turns and repeat

Step 5.

Step 6.

9. Adjust blade guides as described in Adjusting Blade Support Bearings and Adjusting Blade Guide Bearings on Pages 24–25.

— If the blade deflects 1⁄4" or more, the blade

is not properly tensioned. Apply tension to the blade incrementally and repeat until properly tensioned.

Adjusting Blade

Support Bearings

The support bearings are positioned behind the blade near the blade guides and prevent the blade from pushing backward during cutting operations. Proper adjustment of the support bearings helps you make accurate cuts and prevents the blade teeth from coming in contact with the blade guides while cutting. If this happens the blade "tooth set" can be ruined, which will greatly reduce the blade's ability to make good cuts.

Basic Functions

Workpiece

of a Bandsaw

A properly adjusted bandsaw can be safer to operate than most other saws and performs many types of cuts with ease and accuracy. It is capable of performing the following types of cuts:

Straight Cuts

• Miters

• Angles

• Compound Angles

• Resawing

• Ripping

• Crosscutting

Irregular Cuts

• Simple and Complex Curves

• Duplicate Parts

• Circles

• Beveled Curves

Basic Cutting Tips

Here are some basic tips to follow when operating the bandsaw:

Inspection

Some workpieces are not safe to cut or may require modification before they are safe to cut.

Before cutting, inspect all workpieces for the following:

• Material Type: This machine is intended for cutting natural and man-made wood products, laminate covered wood products, and some plastics. Cutting drywall or cementious backer board creates extremely fine dust and may reduce the life of the bearings. This machine is NOT designed to cut metal, glass, stone, tile, etc.; cutting these materials with a table saw may lead to injury.

• Foreign Objects: Nails, staples, dirt, rocks and other foreign objects are often embedded in wood. While cutting, these objects can become dislodged and hit the operator, cause kickback, or break the blade, which might then fly apart. Always visually inspect your workpiece for these items. If they can't be removed, DO NOT cut the workpiece.

• Replace, sharpen, and clean blades often for best performance. Check guides, tension, and alignment settings periodically and adjust when necessary to keep the saw running in top condition.

• Use light and even pressure while cutting. Light feeding pressure makes it easier to cut straight and prevents undue friction or strain on the bandsaw components and the blade.

• Avoid twisting the blade when cutting around tight corners. Allow the blade to saw its way around the corners. Always use relief cuts when possible.

• Misusing the saw or using incorrect techniques (e.g. twisting the blade with the workpiece, incorrect feed rate, etc.) is unsafe and results in poor cuts.

• Large/Loose Knots: Loose knots can

become dislodged during the cutting operation. Large knots can cause kickback and machine damage. Choose workpieces that do not have large/loose knots or plan ahead to avoid cutting through them.

• Wet or "Green" Stock: Cutting wood with a

moisture content over 20% causes unnecessary wear on the blades, increases the risk of kickback, and yields poor results.

• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and often unpredictable when being cut. DO NOT use workpieces with these characteristics!

• Minor Warping: Workpieces with slight cupping can be safely supported if the cupped side is facing the table or the fence. On the contrary, a workpiece supported on the bowed side will rock during a cut and could cause kickback or severe injury.

Choosing Blades

Selecting the right blade requires a knowledge of the various blade characteristics to match the blade with the particular cutting operation.

Blade Terminology

Figure 41. Bandsaw blade components.

A. Kerf: The amount of material removed by the

blade during cutting.

B. Tooth Set: The amount each tooth is bent

left or right along the blade.

C. Gauge: The thickness of the blade.

D. Blade Width: The widest point of the blade

measured from the tip of the tooth to the back edge of the blade.

E. Tooth Rake: The angle of the tooth face from

a line perpendicular to the length of the blade.

Blade Dimensions

Length Range ..................................... 711⁄2 –721⁄2 "

Width Range

Selecting the right blade requires a knowledge of the various blade characteristics to match the blade with the particular cutting operation.

.............................................1⁄8"–1⁄2 "

Blade Length

Measured by the circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between wheels. Blades will vary slightly even in the same length because of how they are welded. Refer to the Accessories section later in this manual for blade replacements from Grizzly.

Blade Width

Measured from the back of the blade to the tip of the blade tooth (the widest point), blade width is often the first consideration given to blade selection. Blade width dictates the largest and smallest curve that can be cut, as well as how accurately it can cut a straight line.

Always pick the size of blade that best suits your application.

• Curve Cutting: Use the chart in Figure 42 to

determine the correct blade for curve cutting. Determine the smallest radius curve that will be cut on your workpiece and use the corresponding blade width.

F. Gullet Depth: The distance from the tooth tip

to the bottom of the curved area (gullet).

G. Tooth Pitch: The distance between tooth

tips.

H. Blade Back: The distance between the bot-

tom of the gullet and the back edge of the blade.

I. TPI: The number of teeth per inch measured

from gullet to gullet.

• Straight Cutting: Use the largest width

Model G0948 (Mfd. Since 08/21)

Page 38

Tooth Style

Figure 43 illustrates the three main blade tooth

styles:

Raker Skip Hook

Figure 43. Main blade tooth styles.

• Raker: Considered to be the standard because the tooth size and shape are the same as the tooth gullet. The teeth on raker blades usually are very numerous, have no angle, and produce cuts by scraping the material. As a result, smooth cuts can be achieved without cutting fast or generating more heat than other tooth types.

Tooth Pitch

Measured as TPI (teeth per inch), tooth pitch determines the number of teeth. More teeth per inch (fine pitch) will cut slower, but smoother; while fewer teeth per inch (coarse pitch) will cut rougher, but faster. As a general rule, choose blades that will have at least three teeth in the material at all times. Use fine-pitched blades on harder woods and coarse-pitched blades on softer woods.

Tooth Set

Two common tooth sets for wood bandsaw blades are alternate and raker. Each different type of tooth set removes material in a different manner, leaving cuts with different characteristics (see Figure 44).

Alternate Raker

• Skip: Similar to a raker blade that is missing every other tooth. Because of the design, skip toothed blades have a much larger gullet than raker blades, and therefore, cut faster and generate less heat. However, these blades also leave a rougher cut than raker blades.

• Hook: The teeth have a positive angle (downward) which makes them dig into the material, and the gullets are usually rounded for easier waste removal. These blades are excellent for the tough demands of resawing and ripping thick material.

Figure 44. Common woodcutting bandsaw blade

tooth sets.

• Alternate: An all-purpose arrangement

where the teeth are bent evenly left and right of the blade.

• Raker: Three teeth in a recurring group—one

bent left, one bent right, and then one that is not bent. The raker set is ideal for most contour cuts.

Blade Material

Bandsaw blades must meet two requirements: flexibility and hardness. The flexibility of a blade allows it to travel on the wheel as a band, while hardness allows the teeth to cut and hold an edge. Modern materials technology has allowed bandsaw blades to meet these requirements in various ways.

Carbon Steel: These blades are differentially heat treated to provide hard teeth that will hold an edge, and yet be flexible in the back.

Bi-metal Blade: A strip of high-speed tool steel is precision welded to a flexible carbon blade, then teeth are ground into the blade to provide good edge-holding qualities for blades taking a lot of abuse (see Figure 46).

Carbon Steel Blade

Carbide Tooth: Extremely hard carbide is either welded onto or impregnated into the carbon steel blades, providing superior edge-holding characteristics (see Figure 45).

Blade Care

& Break-In

Blade Care

A bandsaw blade is a thin piece of steel that is subjected to tremendous strain. You can obtain longer use from a bandsaw blade if you give it fair treatment and always use the appropriate feed rate for your operation.

Be sure to select blades with the proper width, set, type, and pitch for each application. Using the wrong blade will produce unnecessary heat and shorten the life of the blade.

Blade Breakage

Many conditions may cause a bandsaw blade to break. Blade breakage is unavoidable in some cases, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to.

Blade breakage is also due to avoidable circumstances. Avoidable blade breakage is most often the result of poor care or judgement on the part of the operator when mounting or adjusting the blade or support guides.

The most common causes of blade breakage are:

A clean blade will perform much better than a dirty blade. Dirty or gummed up blades pass through the cutting material with much more resistance than clean blades. This extra resistance also causes unnecessary heat.

Blade Break-In

The tooth tips and edges of a new blade are extremely sharp, and cutting at too fast of a feed rate fractures the beveled edges of the teeth and causes premature blade wear.

To properly break in a new blade:

Choose correct speed for blade and material

of operation.

Reduce feed pressure by half for first

50–100 in2 of material cut.

To avoid twisting blade when cutting, adjust

feed pressure when total width of blade is in cut.

• Faulty alignment or adjustment of the blade guides.

• Forcing or twisting a wide blade around a short radius.

• Feeding the workpiece too fast.

• Dull or damaged teeth.

• Over-tensioned blade.

• Upper blade guide assembly set too high above the workpiece. Adjust the top blade guide assembly so that there is approximate-

⁄8"– 1⁄4" between the bottom of the assem-

ly bly and the workpiece.

• Using a blade with a lumpy or improperly finished braze or weld.

• Leaving the blade tensioned when not in use.

• Using the wrong pitch (TPI) for the workpiece thickness. The general rule of thumb is to have no less than two teeth in contact with the workpiece at all times during cutting.

Ripping

Crosscutting

"Ripping" means cutting with the grain of the wood stock. For plywood and other processed wood, ripping simply means cutting down the length of the workpiece. Beveled rip cuts may be performed by tilting the table.

To make a rip cut:

Adjust fence to match width of cut on your

workpiece, then lock fence in place.

Adjust blade guide assembly to proper height

above workpiece.

After all safety precautions have been met,

turn bandsaw ON and wait for it to come to full speed. Slowly feed workpiece into blade until blade is completely through workpiece. Figure 52 shows an example of a ripping operation.

Crosscutting is the process of cutting across the grain of wood. For plywood and other processed wood, crosscutting simply means cutting across the width of the material. Crosscuts can be 90° or angled using the miter gauge. Compound crosscuts are those where the miter is angled and the table tilted.

To make a crosscut:

Mark workpiece on edge where you want to

begin cut.

Adjust the blade guide assembly to the cor-

rect height.

Adjust the miter gauge to the correct angle

needed for cut.

Move fence out of the way. Place workpiece

evenly against miter gauge, then line up mark with blade.

Figure 52. Example of a ripping operation.

ALWAYS use a push stick when ripping narrow pieces. Failure to follow these warnings may result in amputation or laceration injuries!

NEVER place fingers or hands in the line of cut. If you slip, your hands or fingers may go into the blade and may be cut.

After all safety precautions have been met,

turn bandsaw ON and wait for it to come to full speed. Slowly feed workpiece into the blade until blade is all the way through workpiece. Figure 53 shows an example of a crosscutting operation.

Page 45

Resawing

Cutting Curves

"Resawing" means cutting the thickness of a board into two or more thinner boards (see Figure 54 for an example). The maximum height of a board that can be resawn is limited by the maximum cutting height of the bandsaw.

Figure 54. Example of a resawing operation.

One of the most important considerations for resawing is blade selection—a wide blade cuts straighter and is less prone to blade lead (see the Blade Lead subsection later in this manual for more information).

For most applications, use a blade with a hook or a skip tooth style. Choose blades with fewer teethper-inch (from 3 to 6 TPI), because they offer larger gullet capacities for clearing sawdust, which reduces heat buildup and strain on the motor.

When cutting curves, simultaneously feed and turn the stock carefully so the blade follows the layout line without twisting. If curves are sharp or tight, use a narrower blade with more TPI (teeth per inch) and make relief cuts to avoid having to back the workpiece away from the blade.

Always make short cuts first, then proceed to the longer cuts. Relief cuts reduce the chance of the blade being pinched or twisted. Relief cuts are cuts made through the waste portion of the workpiece and are stopped at the layout line, so when you're cutting along the layout line, waste wood is released from the workpiece, alleviating any pressure on the back of the blade. Relief cuts also make it easier to back the workpiece out once the saw blade has come to a stop, if needed.

The list below displays blade widths and the corresponding minimum radii for those blade widths.

Width Min. Radius

1⁄8" .........................................1⁄8"

3⁄16" .........................................3⁄8"

1⁄4'' .........................................5⁄8''

3⁄8'' ......................................... 11⁄4''

When resawing thin pieces, a wandering blade (blade lead) can tear through the side of the workpiece, exposing your hands to the blade teeth. Always use push blocks when resawing and keep your hands clear of the blade.

Page 46

Stacked Cuts

One of the benefits of a bandsaw is its ability to cut multiple copies of a particular shape by stacking a number of workpieces together. However, before making stacked cuts, ensure that the table is perpendicular (90°) to the blade—otherwise, any error in this setting will be compounded in the workpieces.

To complete a stacked cut:

Align workpieces from top to bottom.

2. Secure all pieces together in a manner that

will not interfere with cutting. Hot glue on the edges works well, as do brad nails through the waste portion. (Be careful not to cut into the brads or you may break the blade!)

Lay out the shape you intend to cut on face of

top piece.

Make relief cuts perpendicular to outline of

your intended shape in areas where changes in blade direction could strain woodgrain or cause blade to bind.

Cut stack of pieces as though you were cut-

ting a single piece. Follow your layout line with blade kerf on the waste side of your line (see Figure 55 for an example of a stacked cut setup).

aligning wheels

Aligning Wheels

Wheel alignment is important for optimal performance from your bandsaw. Wheels are properly aligned when they are parallel with each other and in the same plane or “coplanar” (see the illustration in the figure to the right).

When wheels are coplanar, the bandsaw is more likely to cut straight without wandering; and vibration, heat, and blade wear are considerably decreased because the blade is automatically balanced on the wheel.

Bringing the wheels into alignment may require a combination of shimming a wheel and adjusting the position of the lower wheel shaft.

Checking Wheel Alignment

Tool(s) Needed Qty

Precision Straightedge 3'. .................................. 1

Check wheel alignment, and adjust tracking

knob to bring both wheels into alignment as much as possible. If wheels cannot be adjusted coplanar, use Figure 70 to determine how to proceed with alignment adjustments.

To check wheel alignment:

DISCONNECT MACHINE FROM POWER!

Remove table.

3. With blade on and properly tensioned, hold a

straightedge close to center of both wheels. Make sure straightedge fully extends across rims of both wheels, as shown in Figure 69.

Wheels parallel and

aligned: No adjust-

ment needed.

Wheels parallel, but

upper or lower wheel

is not coplanar with the

other wheel: Move the

upper wheel in or out.

Shimming a Wheel

A wheel that is parallel with the other wheel, but is not coplanar, must be shimmed by the distance that it is not in the same plane with the other wheel.

Tip: Standard washers work well for shimming the wheel because they can easily be stacked to get the desired height.

8. Alignment procedure. If necessary to make

the wheels parallel, repeat this procedure.

The first time you get the wheels coplanar,

place a mark on each wheel where you held the straightedge, then use this position again in the future if you need to repeat the procedure. This assures repeated accuracy every time you adjust the wheels.

Close wheel covers.

10.

To shim a wheel:

DISCONNECT MACHINE FROM POWER!

Adjust upper wheel tracking so that it is paral-

lel with lower wheel.

With straightedge touching both rims of wheel

that does not need to be adjusted, measure the distance away from the other wheel with a fine ruler, as shown in Figure 71. The distance measured with the ruler is the distance this wheel must be shimmed.

Adjusting Lower Wheel Shaft Position

If the lower wheel is tilted laterally (side to side), perform the following procedure to make it coplanar with the upper wheel.

There are four adjustment bolts with hex nuts in the lower wheel bracket, shown in Figure 72, that adjust the wheel tilt from side-to-side and up-anddown.

Note: If you make a mistake during the follow- ing procedure, it can be very difficult to correct. Therefore, it is important to double check wheel alignment (see Page 53), and troubleshoot all other possible solutions (see Troubleshooting on Page 48) prior to adjusting the lower wheel shaft position.

Figure 71. Example of measuring the distance to

shim the wheel to be coplanar.

Remove blade.

Remove wheel to be shimmed. Place as

many shims as necessary to correct gap measured in Step 3 onto wheel shaft.

Viewed From Above

Check wheels at A and B locations (see

3. Figure 73). The wheels should align.

— If wheels align, no adjustment is required.

— If wheels do not align, they require lateral

adjustment (see Figure 74). Proceed to Step 4.

Mark upper and lower wheels with a pencil or

marker to indicate measuring locations (see Figure 73).

Blade lead is usually caused by too fast of a feed rate, a dull or abused blade, or improper blade tension. If your blade is sharp/undamaged, properly tensioned, and you still have blade lead, perform the following procedures.

Correcting Blade Lead

Make sure blade is properly tensioned, and

blade guides are adjusted correctly.

Use less pressure when feeding workpiece

through cut.

Make sure miter slot and fence are parallel to

3. blade line (see Aligning Table and Aligning Fence procedures for detailed information).

Perform test cut with bandsaw.

— If there is still blade lead present, com-

pensate for this condition by skewing the fence, as instructed in the following procedures.

Make a few cuts using fence.

— If blade lead is still present, repeat

Steps 1–4 until blade and fence are parallel with each other.
