I've been taking my time and using an air tool and a sandroll on a mandrel to whittle on the Izzy's grips. Seems I kept getting closer and closer then my hand is now uncomfortable and think I may be binding up one of the muscles in the trigger finger. I know, sounds like a lame excuse, but have read of similar situations.
Seeing as how I don't know squat about musculature, muscle interaction yada yada, does anyone have any tips/hints/pointers or can point me in a direction to further this part of my education? Any overall waypoints in grip carving? I don't do wood for a living just to let you know that I'm starting a bit below ground zero......
