Cutting square corners

Sweet; there's your broach rig. I'd thought of an instructional I downloaded on building a Mauser action when you mentioned it, and another benchrest build I saw. There was a cylindrical grinder locally which would have been a majestic wonder and only $250 but it weighed 5000 lbs so I couldn't do anything about it.

I like making and working on guns more than I like shooting them. At some point -- when I have a level entry shop is my guess -- I want to make a kipplauf or two. Found a raft of patent drawings the other week.
 
It can become a bit of an affliction, gathering tools together!

I am at 3 lathes, 2 mills, a Shaper, and a pantograph engraver, and always looking. But I like to buy cheap! :)

I am pretty darn fond of my Myford Super7 lathe. With a few accessories, it becomes an adequate substitute for a lot more stuff to haul around. It makes a GREAT second lathe, once you have a bigger lathe, too.

Hard to go wrong, learning how to run and care for a couple or three or more decent files, too. Like Rodney Dangerfield, they just don't get no respect! For what they can accomplish in good hands, they don't get the credit they should.
 
Speaking of magwell broaching, there is a way of dealing with the corners if the mfr doesn't want to broach, but uses cnc instead. Drill a hole in each corner. Then mill out the web. Catch is, the metal at each corner is left really thin. In the event of a casehead failure and gas venting down the magwell, the lower won't just bulge, it will fracture.
