[QUOTE="YYCHM, post: 16288, member: 993"] I agree that PCing would probably just end up being a temporary fix. This is my niggle. In order to raise the tool off the work piece requires a full 0.055" reversal of the fine feed dial. That's almost a full turn. Today I shimmed the gear rack out 0.02" and that reduced the play to 0.04" A good 0.02 of that is the mesh between the helical gear and handle seat teeth. I can actually poke the tip of a x-acto blade into the gap present between the teeth of helical gear and handle seat teeth, so there should be some gain by tightening that up. One solution offered up on the web is to peen the tooth faces thus raising the metal some. That's where PCing the teeth came to mind and I attempted that once already but with not having a PC gun the coverage was poor. [ATTACH=full]5855[/ATTACH] I would be happy getting this down to 0.02". I'm open to suggestions. [/QUOTE]
