Triggerman Knob Job Kit TM KJ

Triggerman Designs - Knob Job

Precision Adjustment System Kit.

TM KJ

This piece comes in kit form and assembly is required.
The KNOB JOB Upgrade replaces the plain, loose fitting,
Socket Head Stop Screw with a Micrometer Style Adjustment Screw
that makes the final diameter of the ground Tire
predictable and repeatable!

The screw with the Red Knob is a longer Feed Screw (necessary because of the extra length of the Micrometer Style Adjustment Screw).
The chart that you see in the picture is a record of the results from calibrating your KNOB JOB equipped Truer for the first time. (Some racers like their chart on top of the Grinding Drum Cover.)
