Ok, now what do I do?

R1FAL · 03-19-2011, 02:32 PM

hi all,
well, I was pressing my Bbl. in just a min. ago and pressed it too far into the trunion... so how do I press it back out-AK-Builders pressing jig isn't long enuff to go in w/ the rec. on
do I just get a longer bolt to press with? or...???

thanks again,
Dan

ETA: needs to go back out about an 1/8th or a little more- not much (I hope)

A large brass drift and an air chisel with a hammer attachment should be able to bump it out from behind. For a brass "drift" I use a bushing (bearing) from a asphalt spreader but anything similar, should work. There are some other methods people use.

thanks for the suggestion but, I don't have an air hammer, just
a hyd press (harbor freight). and AK-Builders tools- can't put another tool in my budget right now

is there any other way to do this?

Option 2 - reach through with a long socket extension or metal rod. You need a copper or brass buffer to protect the breach. It could be a stock of pennies, washers, brass nuts, whatever. Whack the rod/extension with a mallet/hammer. Be sure not to let the rod/extension get off the pennies.

Option 3 - I bought a long 3/8" bolt (I think it's 3/8" I suck at remembering numbers) and double stacked two brass nuts on it. That way I can tighten them against each other and lock them in place plus easily replace them as they get beat up. You could use threaded rod, etc. Definitely double check the diameter - I may well be off about the 3/8" comment. You then hit this assembly with the hammer/mallet to drive it forward.

Do a few hits and check, a few and check. You may not need to hit it much to get back where you want.

ronin,
SWEET! a long socket extension sounds like it may work!
now if I can get one long enuff..

heck, I may be able it use it W/ the press.
time to take a trip to sears tonight

I'll run over to the shop and get some measurements so I don't
F *&k this up

I'll post more in a bit...

Ronin, Hey I owe ya a beer!

put her in the press and -BINGO! dropped right into position. pressed the Bbl. pin in and finished riveting the rear trunion.

a BIG thanks to ya,
Dan

Must have been a US barrel build? Otherwise you woudl have allready taken the barrel out to begin with and known how to do it?
12mm socket, couple pennies and a 3" extension is how I have always done it. ( using the big F hammer method)

Glad to hear it worked Dan!! I'll add one Shinerbock to the tab :-)

Have fun with your build!

Knall,
nah, orig. Bbl. on a Polish UF- My first AK Build- so I was cautious.

most of the builds I've done didn't involve pressing so I was movin slowly there.

I left the rear trunion *just in case* glad I did,otherwise I think it woulda been harder to press back it where it belonged.

you guys with a few kits under your belts know the tricks, this was my first build in six years & I was a bit rusty
