Breeching up washer

[tbonesmith]

I have needed a .075" breeching up washer for a No4 7.62 barrel, but after some have been back and forth to England and I've still not found one and I can't get one, and I got over it. I thought I'd get a tool maker to do one for me but I thought instead I'd make it myself. It will be good practice on my lathe and I'd make some new tools.
Any way I used a flogged out No4 barrel, so I suppose the materials the right stuff. It took ages, but next time I'd do it a lot quicker.
I was after .075 but got .080 thickness so if necessary I'll just relieve the barrel shoulder by .005", and that should also help to keep the washer held centrally, we'll see.
Anyway I'm glad I took the time and did it, after all I bought the lathe to make this sort of stuff. Here's the process:
