Stuck RPK pin

[TheWabbit]

I have a pin stuck in the barrel ring of the old RPK that is rusted, deformed, whatever and refuses to budge (barrel stub is still in it). I've tried tapping it nicely, penetrating oil, heat. Nothing seem to make it budge. One problem with tapping is keeping the ring steady and in a good position for a good tap (it is round and wobbles).

My only option appears to be drilling it out with a carbide bit, once I get a good solid lock on it unless anyone else has another idea to try.

take a block of wood and a dremel and cut it so you have something solid and properly cut out to keep the ring from wobbling. Use heat and kroil. Make sure the surface under the "block" is a solid surface. anvil, concrete ect, and not a wood bench top, unless its substantial. also use a steel punch and a ball peen hammer, the brass gunsmithing hammers don't transfer enough energy.

also, it would help if you would ask a question in the OP. you just made a comment so I am not even sure if you were soliciting advice to try before drilling it w/ a carbide bit.

I wasn't sure if there was a question to ask. I was tossing it out there to see if someone came up with something. Thanks for the idea. I'll let you know if it works. I really don't want to drill, especially something this small.

I agree with not drilling.... there is a very strong possibility of breaking a bit on this one.

It's not out yet but I had to start drilling it out...very slowly. Heat, Kroil, steel punch, the wood block over the anvil, nothing would work. The wood block has made it stable enough to drill out.
