    Weren't they commonly reffered to as the stench gun?

    Here's my pictures of my current progress on my plumber's abortion, aka stench gun, aka the STEN:
    I threw in the bolt to make sure that it would ride through the tube, and lo and behold, it rides without issues.

    The receiver originally had a stencil pasted on it, which you use as a guide on where to make cuts. I started with my drill press to make the holes on the corners of each section and used a dremel to cut out the metal between each drilled hole. I left some material around the borders of each section of the stencil and went back with a file to flush my cuts up with the stencil's border. I think this led to some of the gnarly look of my cuts as I had a lot of filing to do and went a little too far on certain sections (i.e. I filed into one of my curved which makes it look uneven). I do wish I had a milling machine as that would had created a cleaner receiver.

    I still need to go back and weld in the barrel nut and ejector before I can weld it to the lower receiver, but that probably won't be done for another month (too hot to work in my garage and still need to set up a welding station). Once all the welding is done, I am probably going to finish the receiver with hot bluing even though that isn't historically correct (I like the look of hot bluing).

    So far, my opinion on building a STEN is that is it a straight forward build, but if you don't have a mill, it will be a labor intensive build as you are going to be doing a lot of filing. Not enthused about my handiwork as every cut has imperfections, but it's my first time building a firearm like this with hand tools. (Also, my day job is a software developer. This is my hobby, so I am definitely not an expert and obviously have areas to improve in) I have a MkII and a MkIII to build, so I'll be looking for a milling machine in the future when I decide to build those.

    Tools used so far:
    Drill Press:
    Dremel 7300:
    Hand Files:

    Part Kit: (got it on sale on the 4th of July, so prices might go down again)
    Semi-auto parts:
    TheDan and V-Tach like this.

    Looks fine.......when you get a finish on it the little imperfections aren't noticeable....

    Welding the ejector was a challenge for me on the MK II............

    One thing you need to look for on a possible kit is that it still has the tabs intact on the trigger housing....not impossible to weld the receiver tube without them a heck of a lot easier with.............
