Use a die grinder to carefully grind off the old rivet heads Peel the old trunion off in a vise (grabbing the old reciever)...
This will leave a small part of the rivet sticking up giving you a point of reference for drilling later.....
Then remove the barrel pin :twisted: If you have a press that is the key..
Update us when you get the reciever off....
I almost forgot leave the stock in the rear trunnion, clamp the old piece of reciever in the vise (1 side of it) then twist with the stock after you pop 1 side loose with a screwdriver(read prybar) :twisted:

Demilling without a press - even for impossible Romys

Try a 6 inch vise, a 3/8 socket ground to fit the trunion side, a really short 1/4 in. push pin, plus sucessively longer ones, and a piece of pipe on the vise handle. Torque it down until the pin ALMOST buckles. Then whack the movable end of the vise with a big hammer or hand sledge. It'll probably move a touch. Use longer pins as needed. My worst case was a Tantal that needed a pin, made from a piece of a 1/4 in. drill shank, so short I only got in 2 vise cranks before putting in a slightly longer one. The push pin got squashed, now looks like a little barrel.

Of my 3 Romys, one came out by hammer and punch easily, one in the vise with difficulty, one almost as bad as the horrible Tantal - and its barrel galled the trunion badly when removed, it was so tight. Only one gave an audible pop, and all the tough ones fought me all the way.

Pushing the barrel was similar, one with a hammer and socket, the others pretty tough using the Autozone pulley puller in a vise and a big long wrench to turn it. Just be sure to shim the barrel breech so you get a straight push.

BTW, I heated them, soaked for a week in PB Blaster, froze, used receiver heating, air hammered - didn't help until I got the monster 6 inch industrial vise, made short push pins and cranked and whacked.

Also, push from right (looking forward, to left. My pins were tapered a bit less than .001, assuming it didn't happen from all the hammering!
