PPSh 41 build--Shotgun News

IF these things are uncontrolled for export purposes, not regulated in any way, then anyone could export them. Yes, many US businesses simply are not interested in any export sales.
Punching the various holes would require production tooling. Blanking holes of those sizes in steel that thick would require real punches and dies and a large punch press. There are formulas for calculating the tonnage of press required. Cutting them would be practical. A mill would be easiest. Chain drilling, cold chiselling, hand grinding and filing would also work.

FWIW, Coldsteel Solutions won't export.

Anyway about Cold Steel I have read this on prexis forum (USA):

--- SNIP --- They did have a problem about two years ago when someone broke into their facility and stole their forms for most of the receivers they made. They rushed to replace the forms and in doing so, went out of spec. From what I have heard, they fixed he problem and are pretty close, if not right on for spec now.

And a little further on the same topic (from Britcopinaz):

Myself and Rocco have great $300 paperweights from CSS.

( I think they were supposed to be MG42 80% ers)

do they have any higher rez pictures there. i cant seem to find them
 
A solution might just come from there:

2 halves stamped that need to be hollowed and welded together, not just a weld-on.

I had some time today between jobs on my CNC mill so I tried out my program I wrote a while back for these. They came out so well that I wanted to share some pics of them. The cycle time is about 24 minutes.

I was thinking about doing a short run of them and seeing if anybody might be interested. I'm not sure if they would be prohibitively expensive. I'll have to see how it goes.

A side thought. If these were in steel - wouldn't they weigh a lot more than stamped units???
These are machined from 1018 mild steel. They look a little light in color because I ran them thru the tumbler to deburr them. As far as the weight is concerned, it will probably be a little more only because of the design I have in mind for the inside. I'll post more pics when I get that far.

Do you guys think that in this configuration hollowed out these would really be a saleable item? I know a lot depends on cost, but I was wondering about demand.
Thanks

Since there is no trunnion, and there is still drilling/milling to do (The openings in the shroud) this is not yet a frame I think. Am I right?

I would think you are right, they are simply "funny shaped metal" with no apparent use (except to the trained eye who can see them for their potential). But not being hollowed or anything should not qualify it as a receiver, partial receiver, or any of that, too much work to be done.

You guys think that they could be used in the making of stamping dye's? Or maybe you can make some sort of "casting dye" from them, as they are already in the shape you will need...?

Nice find is all i can say, look like they could have more potential than just making a single barrel shroud, although it looks like they require a lot of milling!
 
well i started on a test die set. looks promising but possibly a little weak. this is a test die so improvements can be made. I wanted to make sure that the product comes out on size. The set is roughly 4" long and made of 6061 alum.

the female half is done, the male still requires shaping.

test die set complete. The test part was formed in a 5" vise.

the shape of the test part is spot on the drawings. now if it was only 20" longer :)

Looking pretty darn good man, getting me excited :D! I don't got me a ppsh41 kit, but maybe i could use stampings one day to dress up my paintball gun...
 
i dont have a kit myself. if i cant find one cheap ( i wont) ill make the rest and look for a surplus barrel. or make the barrel too, depending on availability and price

Well, you could always go through the effort of buying an american parts kit, and paying Questar to import the parts for $800 lol! I think they'd be able to do that? Or perhaps Wolverine Supplies, their ad says "importer"?
 
im not going to bother with importing anything. if i don't find something in Canada ill build it. its not an overly complicated design to copy , but a few stampings may prove a good challenge
 
There is one thing that puzzles me:

As C/As were accepted as "not being readily convertible", WHY couldn't we legally just change the receiver and have it accepted as semiautomatic civilian versions? The mechanism IS already accepted by the CFC/RCMP after all, if not the C/As which we would have "traded" the receiver from would have been ordered destroyed. Right? :confused:

New receiver, new serial number and technically it will "never have been" an smg as the saying "Once an SMG, always an SMG" applies to the frame and this is why we can't use the original maghousing on the Semiauto Sten builds as it is considered as the frame.

Or am I missing something here?
