Semi-Sten: CFC AND RCMP approved and Home at Last

The vast majority of the parts can be found inside any Sten dewat. The tube and bolt are different. The SAS design isn't that complex and could be duplicated fairly easily by someone with the proper machinery.


Don't know about a dewat necessarily being a good source of parts - if one is deactivated to current standard, the barrel, barrel seating, bolt, trigger mechanism, magazine well and trigger housing will be useless, having been welded into one piece with the tube.
An old spec. deact would yield more parts.
A registered 12(2) or (3) gun would allow the harvest of the most parts.
 
Yes, that would be an excellent start, anyone interested in one of these projects could do a lot worse.
Realistically, making up one of these isn't a kitchen table job. A Sten or 3008 is close to being among the simplest repeating firearms ever made, but they were designed to be made using industrial equipment and processes. Some degree of metalworking skill and access to the right tools is necessary, even if many of the parts are available. Stencollector knows what he is doing, has access to the necessary equipment, and even then making the new magazine housing assembly shown in the photo thread took hours and hours.

Tiriaq, you give me too much credit and could scare away others who want to build these. I am an amateur. My tiny workshop (at present) is a 12X20 room. All that was involved with making the magwell was a block of steel, an angle grinder, a Record 6" vise, an oxy acetylene set, a mig welder, and a 4lb mini sledge. The lathe too, but that was really for cosmetics as much as anything else.

There are shortcuts that can be made to the magwell. If one can find some tubing that is close to the inside diameter of 1.5", then you would not have to make the tube part of the magwell. That would save a fair bit of time. I think, between the heading to town to buy the metal and then making up the mandrel, and forming the metal from scratch, I wasted a lot of time. I also did not go light, but rather over thickness on my metal and then turned/ ground it down to thickness. As I said before, a person could easily use metal of about 15 guage for the rectangular portion of the magwell, and that would likely be strong enough, and a lot easier to work with.

Make no mistake, if you live in an apartment, and do not have access to a workshop, then you are going to have a tough time building the magwell, or any other part of this gun for that matter. While most of the work can be done with a dremel tool and a hand drill, there is welding involved.

As Claven pointed out, I am parting with a couple kits on the EE. There will be no bolt included (but the extractor is), the change levers will have been welded to semi, and unfortunately the barrels are all nipped. The maqwells have been cut in half with a chop saw, in such a way that they can be used for patterns, but not as a magwell.
 
Ok... so how long until someone in Canada starts bringing in "new" Semi-Auto Stens?? :D

This was a childhood gun that I've always wanted... I even "almost" bought a dewat to fulfill that need a couple years ago.

I think you will be waiting a while. No manufacturer makes semi auto stens. other than the do-it-yourself kits.
In the US there are full autos made up on registered tubes (they can't come here) and semi autos made by individuals, but those would be prohibited here because of the recycled magwell.
The alternatives are to pay $2300+ for one of the Marstar BD-3008 (which is about as close to a semi auto sten as anything else manufactured) or else build your own for between $600 to $800
 
So, to summarize, one would need:

-1 A parts kit (cost including shipping and customs?) OR a DEWAT (the first one yielding more usable parts anyway)

-2 A SAS3 kit 279$US (+ shipping and customs)

Are we still in the 600$ to 800$ canadian range? :confused:

Not to say the welder needed and either a milling or at least a Drill press + maybe a Dremel and various files.

Did I forget anything?

Yep. Customs is NOT applicable as you cannot, as of now, order a parts kit from the US. Only source I know of is Stencollector - speak of the devil!

You forgot the work and skill and welding and metal fabricating skills that Stencollector put into this project...not many of us are up to that, at least I know I'm not.
SAS3 kit? I believe you'd need an export permit and import permit, which also takes time, if they even approve it. Sigh.
 
well oce the FRT is updated you 'could" with proper paperworki import a sten kit minus the bolt(bolt is for FA use only) as the kit would not be exclusivly for fullauto now that a semi exists......

am i right here??


of course the us wont approve a sten barrel for export as its non sporting under 16"

My estimate:
1) Sten parts kit: $300 (available on the EE now. :) barrels are cut though :( )
2) SAS-3 kit $279 american pesos
3) mk2 barrel $125 (give or take...available in the US for $50, but I have seen them for up to $150 here) or about $240 for a barrel blank to make a non-restricted length barrel.
4) plate for magwell and metal for mandrels: $20

The cuts on the receiver can be made with a hand drill and dremel tool. Not ideal, but it can work. But you will have to have access to a lathe to clean up the barrel trunnion, and a welder (mig or oxy acetylene) to attach the trigger housing and make the magwell. If you are buying welders or drill presses just for this project, then maybe you had better reassess it. But other than the magwell, the skills to make this are not very high. This is sold as a DIY kit, and hundreds or thousands of guys in the US have made these kits. The magwell is going to be a huge stumbling block for many guys. This is what takes this project from the kitchen table to the home workshop.

By the way, I got my certificate for the gun today. I tried to get through to my local FO so he could give me the FRT number, but couldn't get a hold of him today. I'll try again tomorrow.

Just to confirm, the certificate says:
Make homemade
Class restricted
Type Commercial Version

I have a few other things on the go right now, but maybe next month I'll assemble another one and show the step by step assembly, so guys can gage just how hard it is or isn't. Yes, you will need hand files, but I cant imagine not owning such things. I have always felt that the money spent on a tools is usually paid for the first time I use them and not have to pay someone else to do a job I could do.

You would not be able to bring in the magwell either as that is exclusively for a prohib and also considered the MG here.

You can make 3 barrels from a blank....blank costs $240, so each barrel would run $80 and a bit of time on the lathe. The USA is not the center of the universe.
 
Some guys have been notifying the CFC before they start a project like this. Wouldn't hurt...that way if someone calls the police that you are building SMGs in your garage, you would be better covered. There was a thread about this in the discussions forum, where a guy was a week from finishing one of the 1911 frames when his wifes friend phoned the police. They raided in full force, and charged him. In the end, after paying lawyers fees, the stuff was ordered returned by the judge, but he has a firearms ban imposed on him through the Crown.

Personally, I always made sure that any telephone conversations with the CFC were confirmed by a follow up email.

Thank you a lot for all the infos you're sharing with us ! It will help a lot for thoses who want to follow the same path as you did ..

That being said,i just can't wait to see the making of a STEN :D !!!! Especially the preparations needed to use a barrel blank (knowing where to get it would be nice as well)..

Again,thank you a lot for sharing !
