MX 10RS adjustable comb coming loose. I tighten it down pretty snug, trying to not strip it out. Do I need a new set screw or alteration of comb hardware?
One thing you might consider is spacers. Make them large so the torque generated by your contact with the comb is born over the surface area of the spacer rather than relying on the point contact of the screws. One set for each height you need, I don't change my comb but do have large diameter Acetel spacers machined to the correct thickness to accomplish this.Check the base piece in the comb. If the screws have been in an out time an time again or over tightened it may have cracked
You really don't want or need the set screws to dig in that much, and depending on the clearance b/w the post and comb insert it can make them an absolute bear to get off. You're better off going the other way and using steel posts and brass or nylon tipped set screws.won`t a cone point set screw work? are tempered pretty hard like 50 rockwell,should dig in nice.
