I took a break from the Gat project since July and returned to it about a week or so ago. The cocking mechanism is completed and installed. I assembled one bolt (all bolt parts are made) and tested it. It cocked and fired a blank. I am now assembling the remaining bolts and shaping the firing pins, two more to do. I tested all the assembled bolts and they function as intended.
Today I fired a 3 round burst (blanks), its so quick it sounded almost like a single shot. I can\'t fire normally yet, I have not made a top cover or mag at this point, but soon ! I am going to give a whirl at 3d printing a top cover and mag for test purposes, that should be interesting. I got the 3d printer last year, assembled it and tested it quick but have not done anything with it yet.
I have a few things to tidy up, gotta make the bolt insertion knob and knob for the cocking switch. Right now I just have a setscrew shaft collar on the cocking switch, no spring but it works just fine that way.
More to come........... ( PS I got a whole coffee can of blanks at a local flea market for $5.00 this summer, perfect for tests)
