virgin m92 questions

[nicitaja]

People like nicoroshi, yari, and mach69 (to name just a few) Would be happy to hear about any of your notes with respect to the virgin front trunion, and drilling of rear trunion.

So far, I figured out the front trunion follows standard romo rivet hole location, yet the barrel pin location isn't documented anywhere I've been looking? From 2007, The notorious John (who has disappeared it seems) from JCD Tactical Law Enforcement Sales has documented that the front barrel center point horizontal plane (parrallel 0plane) to the front rivet hole is .5100in, but he never mentions how far back parallel to the front of the trunion the center point is (see pic 9/10 from thread at http://www.akfiles.com/forums/showthread.php?t=28802).

I'd love to know how far from the front of the trunion this axis is. The rear trunion is easy to mill out using a akb m92 flat or m70ab2 flat, all though it takes some time, the layout is there. The front trunion I can't find spec for?

Anyways it's been 5 years since John did the "virgin m92" write up @ the files, I'm sure others are doing them, not everyone is sending them off? Anyone pinned a fake can to the sbr length barrel vs. using the 16" and just being able to screw it on. Im thinking that blind pinning and using basic aluminum fill rod melted with a oxy/mapp combo torch (dont have a tig/mig) should do the job, ideas here as well?

How a'bout posting your build notes to help those of us who have picked up one of the many m85/m92 's that are all over the place...

Looking forward to your notes, I know lots of you have done them (nicoroshi comes to mind, the guy must have every Krink ever released)..

Again, unlike most of the other builds, the info seems to be scattered all over the place, yet I havent been able to locate the center point of the barrel pin to drill the trunion.

Thanks in advance, much appreciated.

I was just measuring the barrel pin location for Tujungatoes for a project he's doing.
The barrel pin sits 10mm back or .393" for those so inclined. It is also 26mm (1.023") up from the bottom of the trunnion. This is based off my AMD65 pistol. I would hope the Yugo's are the same.

John You're just a few minutes away from me If you need that can tig welded bring it over. I would not want to see you melt your can with a torch. HAve you used that fill rod before?? I've never had any luck with the aluminum solder crap. So I went out a dumped a bunch of money on a Tig.

Barrel pin hole for the front trunnion I located by coming off the top of the barrel hole on the front, and transferring that line over to the sides. I centered the hole on the small square side (left), and copied that to the right side measuring off the front of the trunnion.
For the rear trunnion I riveted it in place in an AK-builder receiver that had the hole lay out for the underfolder assembly. I then drilled the centers, and cleaned the inside with a dremel to the hole that was in the receiver.

For people wanting to take the easy way out,I beleive Pat from resoreit.com is populating and doing all machine work on these kits(M-92,M-85) for a mere $100.I have bought tools from him and the quality was excellent.If you want the challenge of doing it yourself,I imagine he would also share information.Seems like a good guy.Good luck

I've dealt with Pat and is a nice guy but I was told recently his lead time is 4-6 weeks.

I am finishing up a large order should ship end of next week , then turn around will be 3 weeks . I am offering a service drilling the rear trunnion holes and the rivet holes and spot a barrel pin hole on the 92-85 stuff.

So 3 weeks for kits .

1 week for just the trunnion work.

not following this, maybe I need to spend some time visualizing it, maybe you typed it wrong, "coming off the top of the barrel hole on the front" <- im trying to figure out the location of the barrel pin hole, you mean the front 4mm rivet location?

Okay, you mean the top of the "barrel hole" as in the front of the trunion where the barrel is inserted, think I follow now.

you drew the horizontal line in the trunion where the barrel is located, and then centered that between the top of the trunion and the plane where the barrel is inserted. That gives me the same .5100 from johns thread, now, how far from the front edge of the trunion back to give me the perpendicular line of this center location?

lemme think, maybe you said it and Im just not reading it.


(KCSCOTT) I'm gonna take you up on this, I have this m92 and a tula krink / bluejack barrel pb5 can to do as well. PM me please, always like to meet neighbors with the same passions...

Thanks Pat, good to know, maybe you could give me the center location of the hole? BTW< still use the tools I bought off you, great ideas from a great mind...

Does this make more sense???

Top of barrel hole is center line of pin.

About .400 from face of trunnion or center it on the trunnion boss.

Yup, thanks a million.
