My cannon assembly was very tight fitting to my frame, so last night I stripped the frame down and lapped in the barrel extension. It turned out quite smooth. I cleaned the lapping media off with solvent and scrubbed the parts with a stiff brush and soapy water, then blew the parts dry with compressed air.

This is how the 'thick tang' sideplate fits. The takedown lever is sloppier than I would like (side-to-side) in it's cavity, but it's what I gots.

I don't want to force the lever up any more than I can move it with my thumb. As is, I have to move it down with a clothespin half to get it disengaged.
