I'm looking for suggestions, guys. I'm building the 2nd gun of a second set of matched pairs. This is a Caspian frame, Colt 80 slide, Kart NM barrel. The frame bed needs to be lowered .015 -.020", which is a lot of steel to remove accurately. As it sits now, the bed is so high that the slide wedges the barrel onto the frame as it's retracted.
I'm assuming for the moment that the slide is ok, but I am gonna check that before lowering the frame bed. Also, I've checked and the barrel does not drop far enough in the slide yet, so the slide/barrel will have to be relieved as well, but it does drop farther than the frame will allow when assembled. Using a loose fitting 'work' bushing so that isn't the problem.
Anyhow. Does anyone have a reliable method to remove metal to lower the frame bed? (From feed ramp to the end of the rails). Doing it with a round bar and emery cloth is ok for a couple of thou, but not for this much. No local access to a milling machine / operator I trust for this.
