Nail on the head. The one in my E/S is in decent shape and I have a workbuddy who is talented with a mill. (Gunsmith) We're going to make a few out of aircraft aluminum and then test in my machine for suitability. The original was plastic for a reason. If it was to keep it cheap, there should not be a problem. If it was for to be easy on the other part of the mechanism, it could be a problem. (Wear and tear, etc.) He's going to work on it over the next 2 weeks while I am out of town. When I figure out it'll work, I'll do a quick poll to get a run estimate and figure out a decent price point.
