CAUTION:

- Always use SAFETY GLASSES to protect eyes from chips.

- Tighten chucks securely to avoid unscrewing during operation.

- DO

NOT

slow lathe with hand

on

pulley.

- Operate chucks in excess of middle speed with care.

-

DO

NOT

have the belt tight as this causes the spindle to

stop quickly and may cause the chuck to unscrew.

CAUTIONII

Always Wear Approved Safety Glasses
when Operating Lathe. Tighten Chucks
Securelyto Prevent Chuckfrom Unscrewing.
Do Not Slow Lathe

by.

Placing Hand on
Pulley. Do Not Over Tighten Belt. Keep
Hands Away from Cutting Tool When

Making Cuts.

The

Taig Lathe

is

extremely well constructed

and

requires little'

maintenance. However,

the

lathe must

be

kept clean. After working ajob,

thoroughly clean the

lathe

of

all

debris

with

a soft cloth

and

a small

brush.

Make

sure the spindle threads have

been

thoroughly cleaned

and

oil

the

bed

to prevent corrosion.

If

the

lathe

is

not

to

be

used for extended

periods, remove

the

drive belt

and

cover

the

lathe. Always check lathe

components for ease

of

operation

and

lubricate

as

necessary.

Use

light

oil-10 weight-such

as

automatic transmission fluid orincold weather

WD

40.

Loosen

chucks or faceplate every few days

as

condensation may rust tools

on

spindle, especially near water or

in

high

humidity areas.

Pulley provides six spindle speeds. Approximate spindle speed with

1750

RPM

Motorisas follows:

525 Smallest motor pulley

to

largest

lathe

pulley

825
1300

2100

3350
5300

largest motor pulley to smallest lathe pulley

The motor should sit on an angle
with the weight of the motor

on

the

belt. The motor bracket should
be loose on the board to allow
the motor to be raised in order

to change speeds. Make

sure

the

belt contacts properly.

Acutting fluid (coolant) should be used on all materials. This will provide longer tool life

and a better finish. Water based coolants are not recommended unless lathe is cleaned
thoroughly after each use.

Water

based coolants

may

cause severe corrosion on metal

parts

if

machine is not cleaned well

and

re-oiled.

Carbide tipped tool bits may be used at approximately 3 times the speed of high speed

tool bits.

In sharpening tool bits white

or

gray wheels are used for high speed tools.

Carbide tools require the use of a diamond wheel or a green (silicon carbide) wheel. Do
Not cool tools by immersing in water. This may cause cracks on the carbide surface.

High speed tool bits should not change color (over heat) while sharpening. This will

anneal cutting edge and shorten useful tool life.
Setting tool bits in tool post may require shimming so that cutting edge will

be

exactly on

center. This is

Very Important. One method to determine cutting edge is to machine

across the face of a work piece and notice if the tool bit cutting edge is traversing across
the center of the

work

piece. Tool bit cutting edge may be compared to the point on the

tailstock.

When using steady rest slide steady rest next to the chuck and adjust the brass jaws to
the work piece,

then

slide steady rest to the working position. This procedure allows the

steady rest center

to

match centerline of the lathe spindle.

Soft Jaws may be machined with steps

this.

Reverse Jaws as shown to cut steps.

Advantages

of

Soft Jaws

10 Will not damage work piece

as normal hard jaws

do.

2. Greater accuracy can be obtained when

machining jaws for a specific size and
used

on

the same

lathe.

Remember:

When using any chuck always mark workpiece and chuck
jaws so that the part is

in

the same relationshipifremoved

and replaced in chuck - A good idea is to paint one

jaw

with nail polish.

Part

1200: Top Slide (Compound)

A compound is used for angles and short tapers

on

the work piece. The

positive length may be achieved by having the compound

90 degrees to

the crosslide and by using the dial on the compound to control the length

of

the

cut.

The compound will attach to either "tee" slot of the crosslide and will rotate
and be clamped at any angle. The tool bit is clamped directly on the table

of

the

compound.
