Must be cool to have a brother who's a machinerist!
It is, and he's a good one, master class in fact. We might get the parts made on a CNC machine, but I think the metal will look like it was made on a CNC machine and I might have to finish it by hand. He thinks bluing is a poor way to protect metal from rusting, which from his point of view is true, but they didn't have cadmium plating back in the 1870's. We're both getting an education just talking about this stuff.
Another problem is there's a milling machine I can use to learn and make parts on, but it's in an unheated garage and the really cold weather will be here by the time I get this move out of the way, so it looks like I'll have to wait 'til warm weather before I can get going on this. I want my own shop setup eventually, but that's $$$ I have to save up (and can't spend on guns
).
