Here is last installment of the rivet process. All that is needed once again is the drill press, vise,grinder, punch set and hammer.
To get started, clamp the trigger guard with torched receiver piece into a vise with inside of receiver part facing up. Grind all 5 rivet stubs completey off, be careful not to grind through the thin receiver into the safety selector stop plate.

The receiver piece may fall loose at this point, pull it loose and discard. Bring the trigger guard over to the drill press, secure it firmly in a drill press vise. Be sure to center punch all five rivet ends. Using an undersized drill bit, drill 2/3 of the way into each rivet. This relieves some of the rivet tension when you set up to punch them out.

Clamp the trigger guard into a bench vise, and using a punch that fits into each drilled hole, the rivets are easily tapped out.

This is where you should now be, with safety selector stop plate and trigger guard ready to place on new receiver.

Place trigger guard, with safety selector stop plate, under it, onto the receiver. Be sure that stop part is facing upwards on the selector side of receiver. I begin with the one rivet that is all by itself on the pistol grip side.

Now, get some solid support under that rivet because you're going to take a punch and hammer and flatten the rivet protruding on the inside of the receiver.

Place the last four rivets completely in their holes..........

......and once again, from inside the receiver, using the punch and hammer, flatten and expand the rivet ends.

Be sure to get some good support under both sides of trigger guard as these rivets are being pounded. I straddle the receiver between two pieces of angle iron that are on top of 40lb bars of lead.

With all that work now behind, I call this receiver done!
I will get another black coating on it to cover all those fresh shiny rivets, then begin putting the barrel back in, which will be the next installment as I cover this in Volume IV.
