Question for a machinist . . .
I am thinking of modifying an extractor for my M1882 project. The pin hole will be drilled larger, and a reshaped hinge-bow nut will be set into it - this will achieve the friction-joint with the already bored-out block. I'm thinking of shrinking the two little parts together.
So, when you heat a donut-shaped piece does the hole get larger or smaller? Was thinking that by bringing the extractor to a dull red, and freezing the insert I could get a nice tight fit? Or, maybe just using JB-Weld, or permanent Loctite, would be a better idea?
My tools consist of a drill-press, bench grinder, bandsaw, Dremel, and a large assortment of files!
