AK RSB pin removal

[Baeleron]

Hey guys, I'm trying to remove the RSB from a torched barrel, and can't get the RSB pin to come out. I've tried pressing it out and I've tried pounding it out (3 lb hammer with a solid backing). I simply can't make that thing move. Any ideas? Should I drill it out?

Try the other side. Failing that, drill.

If you decide to drill it, drill undersized and only about 3/4 of the way through.
Then, increase the drill bit size until the wall thickness of the pin is very thin, but without breaking out of the pin and into the RSB.
Now, slip a punch in the drilled hole and drive the pin out.
It will come out considerably easier once you get rid of most of the core of the pin.

I'm having the same issue removing the RSB pin from my AK63D kit, the pin simply does not want to move. I'm using a 55 ton ironworker as my press and still nothing

Is it common to have to drill?

Post a picture of your press setup.

No.
The trick is all in concentrating the force where you want it.
I can't see in your picture if you are trying to press the pin against a pressing block or if there is room under the RSB for the pin to press through.

There is room. I make many mistakes but not that one

Something to try:

If you have an AKbuilder barrel press kit, it comes with that piece that holds the 1/4" diameter dowel pins on the end of your press ram.
Make yourself a starter punch that is 5/32" diameter for about 1/8" and then tapers up to 1/4" where it slides into that dowel pin holder.
Harden the bejesus out of the starter punch.

The more solid your pressing setup, the more force you can concentrate where you want it.

On my press, I have a threaded ram and all my press tooling screws into the press ram so there is no need to hold it, or any worry about it "kicking out" as you have with the vise grips...

[Baeleron]

Yeah it does kick out. I tried making the starter punch with the press ram that you described, but didn't think to harden it. It just mushroomed. I will try again and harden it. Thanks for the idea.

Get yourself a piece of oil or water hardening 1/4" diameter "drill rod" for making all different sized pin pushers that will slip into the 1/4" holder.
Keep them as short as possible for the job that each one needs to do.
Harden them really well.
No more "kicking out"...

^THIS!! Works every time.

Success, RSB/GB/FSB pins removed. I put liquid wrench on them overnight, then managed to press them out using a shortened pin punch. (My attempt at making a custom pin punch failed because I couldn't harden it enough for it not to bend. Probably the wrong kind of steel). They popped pretty loudly when they first moved... they weren't ever coming out by banging on them with a hammer.

Anyway, thanks for the help guys.
