Van Voorhees 22 conversion questions

[Jtm35a2]

I picked up this conversion kit in a lot purchase. Anyone know much about them? Where to find the magwell adapter? I no longer own a mac10 (post sample doesn’t count), but would like to complete the kit and know a little more about it.
And just how dang small does a pic have to be to load it on this server?

I think someone here has the rest of the parts or bought a large lot with that stuff in it. Mitchs friend possibly.

Yes, my buddy has the remaining inventory of sentinel/van vorhees. It was part of a deal where he bought out the old madeacorp. I can get him the magwell adapter. I also have original nylon carry pouches for those kits as well.

I have a few incomplete kits and enough documentation to understand how they worked.

I believe I'm mostly missing mags.

I do intend to put a couple together but I got sidetracked with life and designing a different upper.

 

[Jtm35a2]

Do they generally run good? Or just as bad as everything else?

I have one I bought last year and have been slowly working on. The barrel adapter didn't work in my mac since my trunnion was welded just slight up causing the firing pin to not hit the primer. A guy in my gun club made me a dedicated barrel for it on a new upper which is MUCH better than the little barrel sleeve it came with. It still doesn't want to cycle reliably, so I'm having some weight machined off of it to lighten it up to the Lage M11/22 bolt weight of 238 grams as opposed to the factory weight of 324 grams along with getting rid of the factory STIFF spring and using Lage's. I'll try to get as close as I can to the weight without causing structural issues of the bolt assembly. For the mag, I got the Lage m11/22 mags and sanded the back down and slightly filed around the feed lips and it seems to feed great now with that and a 3d printed magwell adaptor. I'll post some pics of the mag and adaptor since I most commonly hear that getting mags for these conversions are difficult.

Sounds like lots of work lol. I don’t have the interest or desire to make this work for a post sample gun. What’s a fair price to sell this for? I have the bolt assembly, barrel sleeve and 1 magazine.

No idea what they are worth.
About 5 years ago the pieces parts were all over GB for cheap.
Looked like parting one up was more in shipping from the different vendors then the parts cost was.
I have never seen a complete kit much less one that works.

Be kinda cool if one of you owners got some vid proof of these kits ripping a mag out.

I've never seen a video of a working Van Vorhees kit.

Mitch,
Medea Corp is still around. He’s a buddy of mine, who still has a class 2 SOT. (He is clearing out a lot of old inventory though). I believe your friend bought out his supply of Sentinnel parts. I saw Steve Van Vorhees about 6-8 months ago. He’s in a nursing home now. When I told him how he gets mention from time to time, he smiled and thought it was great.

As Root said, these parts were all over GB a few years ago. I bought a mess of the parts, mags, mag adapters, bolts, barrel inserts and it had a like booster washer that went at the base of the barrel insert/chamber.

I dont know what you would call it, it was not a booster that threaded on the front for backpressure, like a little washer floating chamber breach. Practical Solutions 22lr kit used one also.

Got one to work. I found it to be unreliable, get 5 rounds jam, get 7 jam, 2 jam, 1 jam. I gave up completely on 22lr for the M10 series. I could never get a full mag dump with the sentinal or PS. The practical solutions one which was better, but about the same reliability I believe the PS fault was only the magazines.

I got a AM15 Gen 1 upper, its cool, but has faults also. Never could get a full dump, multiple failures on a 125 drum. After 2x 125 round drums (not dumps, bursts) I have to wire brush out flakes and flakes of lead coating in the barrel/bore. Doesnt matter if they are CCI copper coated or straight led 22lr. Relube the hell out of it before I can run again. I think their gen 2 will have the same problem, just will take 3 to 4 drums before having to clean it out.

Old fleming & Vorhees discussions from 2011

M10/45 22 lr conversion

Ok, Did a search, got a ton of stuff... Nothing focused exclusively on a good conversion or drop in kit with a reasonable rate of fire that even SLIGHTLY resembles and functions like Lage product... Any suggestions? panzertruppe

Vids of my flemming running.

M10 .22 kit

I'll be looking for a M10 mac 10 .22 kit here real soon. I don't want the practical soulutions kit as I have a SWR spectre .22 FA rated can. I'm looking for a flemmings or such. I don't think Richard @ LAGE m11 makes one for the M10 ( wish he did everyone speaks so highly of his products) So...

www.uzitalk.com

Looks like vorhees kits were 174 back in the day.

new" flemming kits are only 400.00 bux. I've also found some obscure .22 kits from the 80's that are 174.00 complete and another guy is selling spare parts like a kid @ a bake sale for said kit.

Now everyone wants one and is trying to get them running.

Everything old is new again!

ETA:
I can't believe how long I've had my flemming upper and it still runs great.
And the fact that they were 400 bux just 11 or 12 years ago.
I paid 600 with a ton of spare parts from Sid.T ( RIP )

Yes he bought out the RPB stuff and the sentinel stuff as well as some sten and grease gun stuff I believe. I thought the old man (Chuck I think?) was going out of business but I do see he still has guns listed on GB. His website is long gone. Nice to hear about Steve van Vorhees. Despite what has been said in this thread about the kits being a pain in the butt, they are actually some of the best 22 kits ever made for the Ingram M10. Way better than the flemming and they use the OEM upper. That said, 22 kits of any quality are hard to get running reliably with this platform, lots of tinkering required.

 

[Deerhurst]

The VanVorhees does use the original upper which is nice. IMHO, a running Flemming is the way to go between the two. I wouldn't say any of the part I have are high quality. It's just mostly bent mild steel and a cast bolt all welded together. I've got enough info on them that I've got it 75% modelled in solidworks.


The VanVorhees uses a sleeve in the OE barrel and replaced the OE bolt which is a slick idea. I'm not a fan of the floating chamber but if it works it works. Mine are just a box of parts. Needs all the final machining, fitting, welding, etc. Some parts are missing like the barrel and mag. Mm

I'll probably come back to it but I have a better idea that I think can make work and won't require welding. Gotta finish the design first. Then get materials and make one.

I should add, I paid $20 a pop for the partial kits I have. Bought them a couple years ago.

I would love to hear or read an interview with him. Medea Corp made a number of M3A1 Grease guns, some 1919's and AR-15 conversions prior to the 1986 cutoff. Many of the companies or individuals who contributed to the machine gun registry have dissolved, or passed away. The history of these manufacturers has always been of interest to me.

 

[SecondAmend]

There are brief writeups on the Van Voorhees .22 conversion in "The MAC Man" and in "The Terrifying Three".
MHO, YMMV, etc.

 

[pjm204]

I might be interested depending on price and assuming I can acquire the other needed parts.

Me neither but I’ve seen it in person
