DIY; due to the age of the gun, I couldn't find an ejector online, the gunsmith said they couldn't get one, and their estimate was $100+.greengeek wrote:Nice work Ibidem - are you a gunsmith by trade, or was this a DIY home repair?
I've done a very little bit of metalwork myself (as a hobby).
So I took it apart, looked at how it all fits together, and guessed that I could get it completed sooner if I started filing.
It seems the big thing is to do it in the right order: first get the metal to the right thickness, then cut/grind it to be just a little wider than needed, then take it to the drill press.
After drilling the hole, don't use a Dremel again: it could easily destroy a couple hours' work with a tiny slip.
A set of small files (aka needle files) is essential; I used flat, triangular, triangle one side, and crossing (oval or half round might work as well); a knife file would have been helpful.
The inside edge (the one you see, that the bolt goes over) in particular should be sanded as fine as possible; tiny scratches might be able to catch the bolt. Also, that edge and the shorter end of the ejector need to be particularly checked for fit.
