and the Romys go on.

Hi I feel your pain. Mine finally got drilled out. I just too outhte two pins on the rear trunnion. Only cost me two punches broken and one bent but glory be after drilling them out I pushed the rest out fairly easily. Believe it or not one day I will have a finished kit if I am not bankrupted by all this first. Believee it or not I bent a flat with my version of a poor mans jig and the hole all lined up. Wow! Will wonders never cease. One day it will go bang if not boom.

Could you post a pic of your bending Jig?

I know the feeling. I could have bought an AK for $350. So far, I have close to $800ish in one gun. I just purchased another. So, I have $900 in two. About another 3 kits, and I will be making some headway!

At this point, I wish I would have just bought that damned AK! But, at least this way I will have a little pride when it goes bang (hopefully not bang bang bang bang bang bang bang bang bang bang) :) That would be a bad thing. I ain't goin to jail for no damned gun!

Yup! Yup! Yup!

Man I heard that. Still it is fun to try isn't it. I will have to take some pictures and see if I can get them up for you. I thought about it but just ran out of time. I will try in the next day or so. Actually, it was easier than I thought to make the jig. I figured if I messed up flats were only 12 bucks. I was thrilled when the lower rails actually lined up right and the bolt carrier rode on them.
I felt like Remington or Colt. Still lots to do. I ordered two more kits.

Cheap 7 mm barrel pin

HI,

I made a cheap 7 mm barrel pin by going to Home Depot and buying a 7mm x 50mm bolt. I cut off the head and the threads and had a perfect fitting replacement. Cost 58 cents plus a couple of pennies for the tax.

Torx Socket

I tried the hardened bolt, a punch. About the time I was about to commit Hari Keri. I tried a Torx socket. After some cringing, and standing as far away from the Old 12 ton Press while still pulling the jack rod, a loud “Pop” was heard. I figured “Great” another broken tool. When I looked it had moved. Believe the difference was the wide top of the socket kept the socket straight.

Pushing out the Barrel was easy. 3 pennies “Now crushed” and again the good ole press.

I was at a build party and one of the guys there had the theory that the trick is getting everything square. He uses a variety of washers to support the trunnions so that it was as square as possible to the pressing pin.

I posted pics of what I use to remove the pins here:

The bolt has two nuts on it. One on the inside sets the length of bolt and it is set so that the head of the bolt is flush with the socket head. The second nut is tightened down with a wrench so there is no give! IMPORTANT NOTE, THE BOLT HAS ALL THE FORCE - NOT THE SOCKET!

Now, I have bent a few of these short Grade 8 bolts and then it is time to take the grinder and cut the bolt off and start again but this works for me.

Just add some penetrating oil, line everything up, apply pressure and give the base of the jack a whack with a hammer. Add a little more penetrating oil if needed, add more pressure and give it another whack. Often the WHACK with the hammer is when it will pop!

Once again I brought it to him peened pin and all, it took 2 seconds. He had a larger air hammer than mine, so if you use this method research the difference and buy the big one. I think he said he paid $45, I paid $15 for mine. Oh and use a blunt tip attachement not the pointed one it will save you some heartache.


Something else to think about regarding the Mechanic with a Air Hammer, first if he makes his living as a Mechanic then his Air Hammer is most likely "Blue Point" (made for Snap-On) or similar brand vs. Homier (or similar) and likely cost a lot more than $45.00 The Quality of the tool especially air tool's WILL make a Tremendous Difference! The high end A/H's have a lot more force with larger/heavier "hammers" inside them giving it a much harder blow and far more Shock/Vibration which is what what makes the pin move in this application. (very much like a good quality Dremel vs. a Cheap Dremel) (sure we all know all to well about that tool)

The second thing to think about is that as a Full time Mechanic, your buddy spends a lot of time with a tool in his hands every day, as such when compared to a Hobbyist he is probaly a lot more skilled in using his tool's in general! This is not to take away from the ability of a "Hobbyist" to use tool's. Hobbyist have the advantage of being able to spend as much time as they want on a project without starving to death for it. I have seen some because of this "luxury" do some really beautiful work!
But still, when you use a tool every day, all day to feed yourself and pay for your toys (AK hobby kit's) you tend to get very quick and efficent with said tool's very quick! Most people think a air hammer is a air hammer, but it really isn't, as mentioned, better quality air hammers "hit" harder with more shock. A tool's time in hand and practice using it make working it a art form in it's own way! As a Old School mechanic myself I can say this with a degree of confidence, after all we are'nt referred to as a "wrench" for nothing!!
I just wish that as a wrench at work I could afford to spend the time on a job that I do when at home working on a project!! I suppose that is the difference between a "hobby" and a "job" though, and as such why a project is relaxing to work on in one's free time where-as a job tends to be more "intense" and/or "stressful"!!!!!!
