The thread profile should be checked with a brand new chaser. To check the length of the thread, slide the bar end gauge
over the bar and look to see if the end of the bar falls within
the step range of the gauge.
Checking Threads and Bar End Engagement
If the thread length of the bar is off, the adjustment screw
at the back of the motor is used to make up the difference.
Turning it in, (clockwise) decreases thread length while turning
it out, (counter clockwise) increases the thread length.
If the thread length is off, the proper adjustment can easily
be made by measuring the amount of protrusion from or
recession into the gauge.
Example: If the bar is protruding beyond the gauge by
1/8 inch you would turn the adjustment screw in (clockwise)
so that the touch probe would move forward 1/8 inch.
If the bar was 1/8 inch too short you would turn the screw
out (counter-clockwise) moving the touch probe back
1/8 inch.
A scrap piece of bar should be used to set the bar end
gauge prior to making a production run.
