Grizzly G4003G Tool Post & Holder, Tailstock Controls, Tailstock Handwheel, Barrel Lock Lever

Tool Post & Holder

Figure 37 shows tool post and a holder with optional bit. Cutting tools can be secured and removed by tightening or loosening the clamping screws in the top of the holder. A threaded stud is mounted in the top of the holder and has a knurled thumb wheel. Rotating the thumb wheel allows for adjustment of the tool holder so the cutting tool can be centered. The handle on the tool post can be rotated to lock and unlock the tool holder onto the dovetail ways. The tool post may be rotated by loosening the nut at the top of the tool post.

Tailstock Controls

The tailstock (Figure 38) serves many functions. The primary use is for holding centers and drill chucks. The barrel has a Morse taper #3 bore and is imprinted with graduations in millimeters and inches.

Side Lock Lever & Torque

Tightening

This removable lever locks the tailstock in place on the lathe bed. The socket that it fits into will accept a 1⁄2" drive torque wrench.

For repeating super accurate vertical alignment positioning time after time, tighten the tailstock here with an inch-pound torque wrench. If you must, you can use a foot-pound torque wrench but DO NOT exceed 40 lbs/ft of torque or you may damage the ways and the tailstock. When tight- ening the tailstock down to the maximum torque of 40 lbs/ft, the center point will be drawn down approximately 0.006".
