MOUNTING INSTRUCTIONS

This machine comes with a “T”-nut and hex head screw for mounting directly to the lathe compound. Due to the many
lathe types, it may be necessary to alter or replace the “T”-nut with one of the correct size for the particular lathe.

“T”-nut dimensions are supplied as follows...

1"

1/2-13 UNC – 2B

Tapped Hole

3/4"

3/8"

1-3/4"

Mat’l 303-SS

MOUNTING:

STEP 1. - Remove any tooling, tooling holders, etc. from the lathe compound.

STEP 2. - Clear all chips and debris from the top of compound and “T”-slot.

STEP 3. - Providing the “T”-nut is of correct size for the lathe compound, lift (or hoist) the entire tool into position.

Align and insert “T”-nut into slot.

STEP 4. - Using your fingers, lightly snug the hex screw (P/N 97087) until the tool becomes parallel to the

workpiece centerline.

STEP 5. - The tool can now be swung from side to side and positioned for the desired angle between the contact

wheel and the workpiece. Once this is achieved, firmly tighten hex screw (P/N 97087).

STEP 6. - Position the contact wheel at or above the workpiece centerline. This will ensure proper belt tracking and

prevent chatter from occurring. The position can be altered by loosening the two cap screws (P/N 97088)

and allowing the tool to pivot on the pivot shaft (P/N 65266)

this task!) Firmly retighten the screws once proper positioning is achieved.

The machine is now ready for operation.
