Building the Canadian Semi-Auto STEN

[tiriaq]

Air pressure is a variable with any medium.
Glass beads can produce a fine peined surface which gives a really fine slightly matte blue, not unlike rust bluing.
Sand, aluminum oxide, silicon carbide, glass grit, etc. will all tend to cut more aggressively, once again depending on air pressure. For Parking or coating, a bit more tooth is desirable. If a firearm is somewhat pitted, an aggressive medium at higher pressure will tend to blend the miseries in together, and when finished, the efect is not bad.
Be careful with sand. Depending on the type and source, free silica dust is a possibility, and you do not want to inhale that. A cabinet can be given negative pressure with a vacuum, and this will greatly reduce exposure.

Known variants we know we can make from the SAS-3 kit + parts kits are :

-Sten Mk3

-Sten Mk2 (for the moment the ONLY one with a FRT number)

-Sten Mk V (If you wish I might ask for permission to post pictures of one build here)

-R-5 Gnome-Rhône (well if one feels like it is possible I'm sure.)

-MP38 look-a-like

" A WHAT? " Will you say. So as words are good but pictures are better yet, take a look!












Who knows, maybe the idea is worth digging. What do you think? (comments please) By the way, I have the same images in .pdf format if anyones want 'em please PM and I'll send it (as long as we can insert attachments on PMs here.) Or give me your email so I email it from my personal email.

Posted a big picture update on my thread on the "other" site, but here's a couple that folks might recognize:









A bit of work tomorrow, and I'll be able to go get some more welding done!

Maybe early in the afternoon!

Great news! I received my registration certificate today (June 2nd). Now to have the cert amended from frame/receiver to complete firearm...

It took a little over 5 weeks.

Make = Homemade
Type = Commercial Version
Bbl Length = Frame/Receiver Only

[Claven2]

My cert was ammended today from a frame/receiver to a complete firearm. Though it may still come, there is no formal request in place for RCMP inspection - just a verbal warning that it may happen.

the ammended cert should arrive within 2 weeks.

Now, a question that might just be of interest for those who still hesitate to begin their SAS : Is there any place where to find a template that will NOT need to be touched-up ? Those that are available on the web all seem to need the charging slot placed lower on the tube and a few other minor but still needed modifications. Even the templates from Luna and Diablo's will NOT work with the SAS-3 kits. I know, I asked them in an email and they said so.

You might want to try prexis sten. They have a mkII template available, but you may have to pay a nominal fee for it.

Meanwhile, after having had to touch-up many times the templates available to me to finally have one at the correct dimensions and having practiced my cuts on a cheap muffler pipe, I finally glued on a template that was A-OK on my “good” tube.

I will still have to cut the openings and then make the 2 halves of the magazine well not forgetting to take PLENTY of pictures to join to my application to register a firearm (frame only). Then, when I’ll have received my cert., I will put it all together, WHEN I’ll have found a bolt kit (which I have plans here) and an 18½ inches barrel.

I must expect to be asked to send the final product but hey, it is the last of my troubles so much I am expecting it to be compliant to our laws. Oh sure I could have made the original barrel cut and rebuilt (i twas torch cut) but I wand a non restricted firearm so …


Note here how I had to displace the sear opening as on the original drawing.


I pre-cut the sections to be cut on the template so when I make my cuts, the drill bit won’t tear off the template. Then I colored the bare tube with permanent ink pen as I did not have machinist blue or else I would have used it instead.


As you can notice, the original template came from a Sten Mk5 template.

Today I finally began working on my SAS tube. There are the 3 simple steps I made. I am keeping from doing more work for now as I still don’t have a bolt conversion kit nor an 18½ inches barrel blank at hand.

I already had a rat tail file that was just the right size for today’s job.

Looking good That tube looks familar, by the way...

My lathe will be back up and running next week (still waiting on a replacement drive pulley to complete my rebuilt of it), so I may be able to produce some more tubes if there is any interest.
