The problem is, time is money, and most of my time belongs to my customers. If you look at how long it would take me to do the things that you mention (which I am very capable of) it would be cheaper to just buy these things.Weren't you a Toolmaker before you became a Gunsmith? Why don't you convert one of those Texans or MECs to 10 ga? I think you can handle making the sizing die, and the Wad Guide you could adapt form a MEC and the Crimp Dies as well. You'd be out a few parts from MEC which are generally pretty cheap.
On another note I know you have a nice lathe,,, why not buy some 360 brass rod and make some Brass shells. Pretty sure you could handle the machining aspect, it isn't that hard.
Two ways to go at that. You could either make the hull one piece complete and recycle the brass chips. Do the ID first,,,
OYes, lots of options for a man who has a bunch of machinery, money, and time sitting idle, which I do not.r make the base and solder a tube onto it,, Provided you could find something close to make the tube out of. Lots of cartridge cases are made this way and it is the most economical use of materials. Also you could make the primer pockets any for any size primer you wanted ( like Large Rifle?) What's the OD and ID of a 10ga?
OK, from a toolmakers perspective, I'd better be making over $27 per hour, or moving fast enough to make it cheaper to make it at that rate, than to buy it outright and be done with it.Something to remember,,, All machine tools were originally designed and built to produce Interchangeable Parts for Guns. Engines and Transmissions came later. You already have a Mill and Lathe, look at this project from the Toolmakers prospective and you'll have a good time figuring out how to make this thing kill dinosaurs.
I am curious what you've got yourself into!Just wait til you see what I've been building over the Xmas holiday. You're gonna love it.
