While adjusting the overtravel, it appeared to me that with trigger not traveling as far out of the way (past the breaking point) would create a situation where the sear might rub on the curved face of the trigger behind the sear engagement.....so I was going to relieve that curved area a little deeper so everything would clear and I could keep the overtravel adjusted fairly close.
I was foolish enough to hold the trigger so that the trigger engagement was facing away from me when I started grinding, and promptly got too close to the edge. It was not hard to re-establish a square corner, and I have tested the safety and used a deadblow mallet on the back of the bolt to check it for impact sensitivity.
It is by the way, a Wilton Square Wheel belt grinder...not a belt sander, and I am quite capable of reshaping the sear engagement though that is not what I set out to do. I am also capable of case hardening the part, which is why I was asking if anyone knew if it was just surface hardened.
Jard is the most economical aftermarket trigger option I have found, does anyone have any experience with them?
