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
Securely to Prevent Chuck from 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 a job,
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 or in cold 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 Motor is as 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.

A cutting 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.

• Collets will accept material that is .001 over collet size to .004
under collet size. Bar stock is nonnaJly within this tolerance.

Will not damage work piece
as normal hard jaws do.
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 relationship if removed
and replaced in chuck - A good idea is to paint one jaw
with nail polish.

Sho\vn \vith steps
• Jaws may be cut with steps to
hold thin disks or clock gears
• Thin wall tubes that regular threejaws would damage may be held by
machining jaws to exact size of
tube so that almost 100% contact
on tube will be achieved
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.
PART #1152. DIE HOLDER
• Threads Inay be put on a part \vith a button-die. This is a round
piece of tooled steel with thread-cutting grooves. The dialneters
of small button-dies are 13/16 and 1.00 inches. In this size,
threads may be cut from 0-80 to 1/2 inch.
Die
The purpose of a die holder is to align
alld allow the button-die to cut a tl·ue and
untapered thread .. When scre\ving the
button die on workpiece, always have a
45 degree chalnfer (edge brake) on end of shaft to be threaded.

longer tool life and better
finishes may. be obtained using
a cutting fluid. For steel a
pipe thread cutting oil works
very wen. For alum. or brass
kerosene or diesel fuel may be
used.
The·l220 Milling Attachment provides vertical travel of approx. 1 3/4 inches. The crosslide dial provides travel
in·.001 increments direct reading.
The cutters (end mills) are held in the spindle with the collets to provide maximum ridgidty. Miniature end mills
c~me with 3/16 dia. bodies and various size cutting diameters. The end mills will cut all materials steel, alum.
brass and plastics.
t
Carbide tipped router bits
with 1/4 inch diameter body
may be used ·for cutting alum.•
brass, plastics and wood. They
are not recommended for steel.
Carbide tools should run at least
4 times faster than high speed
end mills of comparable size.
