I am ready to press in barrell on 2 Yugos. What is the best way to support the runion/ receiver? On my Romy I just supported the base of my receiver. Should I put something inside up against the trunion? if so, what? |
| in all the viedos i have watched and the ak builders tools an kits i have checkout you should use an aluminum or brass support. Nobody has said why but I gather since the brass or aluminum bar used would be softer then the truinion so press as hard as you would like and the only one that is going to get hurt is the bar. ......... oh and you should definatly support the trunion through the magazine opening and right through to the open top of the reciever. In one of the tacked topics I must thank the guy who filmed it for the rest of us, and the guy who hipped us to it and tacked it here for us. good luck. |

Check out this tool (at the top of page...no not the girl) www.gunthings.com/galil.htm This looks like it would fully support the trunnion while pressing the barrel in from the muzzle. |

What support....? Oh yeah, now I see it! I thought about those but I need to press them tonite since me and my son are leaving Sat morning for our property in West Texas to go camping and try them out... How do I keep the receiver stright so the barrel goes in true? I amd using a HF 12 ton press and it seems to move all over the place..... |
Ok, I've done this twice with no fancy jig type support, just a big allen wrench shoved through the magazine hole through the reciever, with the trunnion resint on it. And your right of course, it moves all over the place. Far rfrom the best way to get it done, but it CAN be done. Bear in mind I did it alone, with four hands it might have should have bee WAY eisier. (but probably not as easy with a commercial jig) Any way------- First time, Rommy G kit, I got lucky, and after lining every thing up in the press, no heat, no ice, just some wheel bearing grease cause that's all I had, when I started coming down with the jack, while holding the reciever and barrel both with my left hand, it started right in, but a crooked. Stopped, drove it the 1/8 inch back out, tried again, and bingo, it slid right in, not all that much resistance. However, when I got to the proper depth to line up the pin hole, it was off (canted) just a hair, and straightened it out in the vise with soft jaws and a BF crescent wrench. Done. For some reason the AMD kit went together much harder. Could not get it start, it would tip the reciever over at an angle, and I was gonna crush something. After several false starts I took a little butane soldering torch and heated up the trunnion a bit and tried again. It was shoved in a tiny ways, hung up tight but way tipped over at an angle, and I took a mid sized hammer and wacked things with a block of wood to protect things untill it looked straight again, and started pumping the jack gently thinking I was NEVER gonna get it, but it did that time. Started slidiing in nice and straght. Matched up the pin hole, discovered FSB was canted yet again, did the vise and wrench trick, it was done.\ Hope this helps PCM |

Got it. Pressed in both barrels tonite. Put the barrels in the freezer and the receiver/trunions in the oven at 200 degrees for about 1/2 an hour. A little grease and used a large punch to support the trunion on the press and presto, they are together. Even the barrel pins went in nice and slick...almost there... |
