Compound Rest; Tool Post - Grizzly G4003G Owner's Manual

Compound Rest

The compound rest is used to move the tool
toward and away from the workpiece at the preset
angle of the compound rest. The base of the com-
pound rest has graduated scale used for setting
the cutting tool to a specific angle.
Tool Needed
Wrench 14mm ................................................... 1
To set compound rest at a certain angle:
1. Loosen two hex nuts at base of compound
rest (see Figure 53).

2.
Rotate rest to desired angle, as indicated
by scale at base, then retighten the two hex
nuts.
Tip: The first time you set the angle of the
compound rest for cutting threads, mark the
location on the cross slide as a quick refer-
ence point. This will allow you to quickly
return the compound rest to that exact angle
the next time you need to cut threads.

Installing Tool
Tool Needed
Open-End Wrench/Socket 27mm ...................... 1
Hex Wrench Size ......................................... 5mm
To install tool in tool post:
1. Position tool in the holder so cutting edge
extends just enough to allow tool to cut free-
ly—but no more. The cutting edge must be
well supported to ensure good cutting results
and avoid chipping.
Over-extending a cutting tool from the post
will increase risk of tool chatter, breakage,
or tool loosening during operation, which
could cause metal pieces to be thrown at
the operator or bystanders with great force.
DO NOT extend a cutting tool more than 2.5
times the width of its cross-section (e.g.,
2.5 x 0.5" = 1.25").
