Was looking at the You Tube vid and got me to thinking. The axle holes for the CAMS in my castings have become eliptical over time, so that the CAMS can move about quite a bit. Has anyone got suggestions on how to repair them? Should I drill out and use a bigger set screw for the axle (or whatever kind of screw thing that it is) or fill it all in with epoxy and redrill (will epoxy even bond with the casting)?

Appreciate any comments you may have.

Cheers, PT.
