Uzi drum question

[Jtm35a2]

I’m looking at trying my hand at making an uzi drum. I have plenty of suomi drums laying around.
Does someone have a known to work drum that I could get some dimensions from?
I’m looking for the tilt angles. The pics I have seen looks like it is not perpendicular to the drum on either plane.

Contact David Hackenberg at Doubletapfirearmspa. He makes and sells them. He will help you out in making one.

That’s convenient. Davey and I are meeting up this weekend.

Nope, just a droplet of water in a big lake. Just a thanks goes a long way.

I definitely appreciate the help. Thank you. I’m sorta new to the mac/uzi world. But I’m diving in with both feet.

You’re doing great!!!! You’re on the right track!

Thanks. It’s definitely easier putting irons in the fire than getting them out though lol

Check the archives here. I seem to recall some fairly detailed info with photos, angles, etc.

But it was probably 15-20 years ago.

i have a c&s drum which in my experience is the best one ever made. I will be happy to share any info with you. It runs 100% in my RR imi gun.

i am 99% sure it is built off of a Suomi drum.

I have had others that did not run as good.

Here is the conversion thread.

Sadly some of the pics were locked away due to photobucket's added pricing.

Suomi Drum / M11 (RO) Conversion

This is a continuation of the RO/BETA C Drum Magazine Conversion Pics thread. It is a brainstorming thread for those of you interested in converting the Suomi M31 drum to work with the Mac series of firearms. Please read the above, and following threads for some background info on this...

The C&S drum is definitely the best, and here's why. Back in the heydays of Vector Arms, Ralph decided he was going to make a copy of the C&S drum without their knowledge. He ordered a C&S drum intending to copy it, but they found out about his plan. They sent him a drum with the mag tower welded on at the wrong angle to frustrate him. Over time, Vector played around with the angle but never got it right, contributing to the feeding problems on the Vector drums.

Didn't know about that history...that is pretty funny..

Back in the Mike Maguire (who went to prison)don't know if he is out now) was making drums for the MP5 and Colt 9mm by modifying Suomi drums and factory mags. He wanted to copy an UZI drum and posted he would give anyone two free drums if they let him borrow one. I let him borrow one and he said it was too much work. I don't know if it was because you need a longer 'tower' or what. He did give me (2) Colt drums and 1 MP5 drum though.

That's a good one
My vector drum runs 100% maybe they figured it out towards the end

There were definitely several 'generations' of the Vector drums. I have some of that detailed on my site here: https://c3junkie.com/?page_id=498
Pictured below is I think the very first attempts that were for sale on the left and my C&S on the right.

I sent my Vector drum back and got this one back:

Even this one could not keep up with the cyclic rate of my Mini or Micro UZI so I sent it back as well. The latest version used dummy rounds similar to C&S but more shiny.

I would have thought this was a tall tale if anyone else had told it. That's pretty funny.

I do have a vector drum that has done maybe 8-10 flawless dumps, fwiw, so maybe they figured it out?

***EDIT:*** I (may) stand corrected. My drum has the "safety ring" and came with a PVC cap winding tool, so I thought it was a vector, but it has the grey aluminum dummy rounds. Perhaps C&S?

I have only seen the 'safety ring' and the PVC cap winding tool from Vector. Maybe C&S did it later but not from what I have seen. Again, I've seen many Vector drums run fine in full size UZI's but can't recall any that could keep up with the Mini or Micro but that isn't to say that some did work....just not that I've seen.

FWIW, I've used a Vector drum in connection with a VM Hytech magwell adapter in M16 9mm shooting at around 1050 RPM. (One needs to support the drum as the adapter latch isn't able to retain the weight of a loaded 72 round drum).
MHO, YMMV, etc.

Great string. All I can say is we built a bunch of Uzi drums, and they worked.
