Building the Canadian Semi-Auto STEN

[Claven2]

here are some stylish pics of me building the legal receiver (mag well) - I wore a special shirt for Stevo's benefit:


A buddy's third pair of hands helps. Here I am stamping in the serial number BEFORE the receiver is finished. It was registered at the 80% complete stage.

Serial number:

And here we have a "fake" double-stamped LB proof:

And here I am stamping the model markings:

Sadly, I didn't do as good a job stamping "LONG BRANCH" as I did STEN MKIISA:

Markings all stamped in!

***Note that in the photos, the relief cuts in the mag box are NOT cut. This shows the CFC techs that it is a new box, not an original LB box welded onto a collar. The mill cuts were made AFTER stamping***

here are the pics of the now completed and registered receiver:





It's been bead blasted. If the RCMP approves it, I will park it too.

Here is an example of an original early LB sten housing. The earliest ones were handstamped, and the welds where the box meets the tube were cleaned up as well.


Don't feel too bad if yours isn't quite as good as this guys work...he had already done 17 more before this one.

If you parkerize your sten, then it should have a single letter along with one, two or three numbers after it. This was stamped on the magwell, the barrel (under the nut) and the trigger housing sideplates. Not sure if these were batch numbers or inspectors marks. All the park'ed stens from Cdn service had it. You could use something like C08 (your initial and the year)

Actually, that sheet metal tab rotates away under the gun - it's a safety.

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.

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.

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

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.
