I think I got in over my head. I can fuck with Ar's in my sleep, I am going to spend more in time and money on Jigs and what not than this parts kit is worth. Thank you for your videos though!
Awesome video. I was trying to figure out, on a complete gun, can you press barrel out and new one back in with trunion still riveted into receiver, My guess is you can with right tools. Where a good place to find the right tools for this work? Thank you very much. Did great work! 😊
If it's a chore...why are you interested in the process, just out of curiosity? I actually find it relaxing, and when I am done with it, rewarding; but I have never thought of it as a chore.
@abogadisimo The ram size is the press ram size. They come in 1", 1.25' and 1.5". Most get the Harbor Fieight shop presses. So, it depends on the ram of the press...
@ScopedOUT2 It depends on when and where they were made. Russian (and other Eastern bloc) Milled and Early Yugo Milled AK's had threaded barrels. Later Bulgarian Milled AK's were press and pin. All AKM pattern are press and pin, however barrel journal diameters vary by country and pattern (Euro, Chinese, Yugo).
So is the actual trunion suppose to be tight around the barrel or just the rivets sticking out a bit after squishing them? What surface is holding the barrel in place?
So, if the bolt locks into the front trunnion, head space is how far the barrel is pressed into the trunnion's journal? Also, is there a split collet that will hold the barrel in an arbor press, so that I can press the trunnion down onto the barrel? I'd hate to have to buy that giant as H-frame press.
You'll need a set of headspace gauges, pacific tool & gauge sells them you can also find sites that rent them at a very reasonable price. You want it to barely close (i.e., takes a bit of force) on a go-gauge and hardly move at all on a no go. be sure to do this with a stripped bolt that is in it's carrier for most accurate measurement. You cannot use an arbor press, will need a 12ton H-frame at min most builders use a 20 ton. As for specialty tools search for a gentlemen named robert forbus, he makes some of the best build tools for AKs on the market.
what are you using to press the barrel in and where did you get it and how much was it im going to a gun smithing college but i never knew the name for that press
When and how do you adjust the headspace? I thought headspace was set & verified as barrel was pushed into the trunnion. If not, when and how is headspace set?
@elliotle I don't need to listen again. I was thinking that the whole time. :D Dude, you could do ADR for Topher Grace if he didn't feel like showing up. Just a thought.
@762full so is paying 500 dollars for a run of the mill wasr 10... at least this way you can make it the colors you want....i wonder how much accurate an ak would be with a milled receiver
I need to press the barrel of a Chinese MAK-90 into the trunnion. Is there any reason why I shouldn't/can't just use a rubber mallet instead of a press?
Sorry to hear about your troubles with you tube, pieces of shit. I’m having a problem with my Romanian PSL. After shooting 2rds the third round goes off prematurly. The back of the caseing splits, the dust cover blows off and the round gets stuck in the barrel. My gunsmith is not sure what’s is happening, he did say he wasn’t that knowlegable with PSL. Any ideas?
I was 10 years old when this video was posted and now using it as a learning tool in building my first AK. Absolutely bonkers
Same lol😂
I am excited about getting started on my 74 build. Videos like this just fire me up!
How's the 74?
Thanks man, this video actually shows what I needed to see. I plan on building up a kit from an NDS receiver one day.
I used motor oil to mate the barrel parts and installing it into my trunion. Works great. if you're okay with all the gel cleaning afterwards. :D
all these vids are great im trying to fund my first build( 74 )
This help alot =)
I think I got in over my head. I can fuck with Ar's in my sleep, I am going to spend more in time and money on Jigs and what not than this parts kit is worth. Thank you for your videos though!
You should watch how to build an mp5. Makes an AK look easy

When you pressed the barrel. When do you stop pressing, when the barrel pin hole aligns with barrel or you press till you cant no more?
I know this is a little late, but I got a couple of brass ones at the local ACE hardware store.

that was "unethical" what you did with that lube and that trunnion.
Wouldn't you want to also file the chamber edge ever so slightly too?
Kalashnikov was a genius.
Cool where can I get one of these kits to make an ak

Hey. Nice video. Can you point me in the right direction to source that barrel alignment tool?

soooooo..if you dont have a press, how do you install the barrel?
Toth Tools. :D

Nice video.

what press is that?

I don't want to reinvent the wheel so could you tell me how many rungs would be ideal on that ladder?
Do any AK receivers use threads to just screw the barrel on, or all they all press and pin?
@762full so is paying 500 dollars for a run of the mill wasr 10... at least this way you can make it the colors you want....i wonder how much accurate an ak would be with a milled receiver
How do i know the ram size that i should buy from you page?
I have a 1mm flat standard AK-47 7.62 with trunnion hole
thanks
Please help where can i find a type 3 screw in barrel
I need to press the barrel of a Chinese MAK-90 into the trunnion. Is there any reason why I shouldn't/can't just use a rubber mallet instead of a press?
A rubber mallet? Please stay away from firearms, please
@BuildyourownAK real quik im building an ak-74 will all these procedures that you've done with the ak 47 receiver work on the 74?
Yes
Would a 1/2 ton arbor press work for this?
brandonion1985 no. I would estimate you need atleast 6 tons.
hell no
you sound like ammosmith
would a 12 ton press work?
Could you use the 6 ton press?
can you press barrels for other people?
What is the purpose of the t shape tool?
Rafael Garcia I believe the T shaped tool is to distribute the pressure inside the receiver so it doesn’t flex or bend.
maybe to take rearward pressure off trunnion rivets and prevent contact of 1/2”
bracing iron bar from chamber. IMHO
cool
@BuildyourownAK cool thanks
Hi, what kind of metal is it?. stamp tin?
Sorry to hear about your troubles with you tube, pieces of shit.

@BuildyourownAK ahhahaha
@semiautoriflelover then u were looking at shitty AKs :/ sorry to say.
Are you a guy?
what type of press is that?
