Great stuff so far. That bolt holding tool for compressing the ejector is a piece of work....very nice.
AFCarbon15........where are you?......(crickets chirping)
You've posted some pretty cool stuff in the past, would like to see you re-posted some of it here.
Here's another one of mine.
Anybody buy one of those steel receiver puzzles, ya know- that bag of flat metal parts you got in the mail and now it's laying in your gun cabinet?
I have one for a rainy (or snowy) day project but started doing some pre-planning on how to put it together correctly so it is square and true.
I figured the most important part is the fire control group area so I figured I'd get that right and work from there.
I had some threaded stand-offs cut to .700". Used M4 screws for the trigger and hammer pin holes (M4 screw has a nice fit in a 5/32" hole) and a standard 3/8 bolt for the selector.
Blueprint spec for the width on the fire control group pocket is .690" but when you stack up the metal plates that have to fit between the two receiver sides, they equal about .700.
So I figured I need to stick to how this receiver was designed and ignore the spec. We are only talking about .005" on each side so I did not figure it would hurt anything.
When I tighten the screws hopefully this will minimize distortion when I weld it together.
