Building the Canadian Semi-Auto STEN

[Mick]

Mick, the slot was cut narrow enough to keep the disconnector in position (in theory). If it doesn't function in practice, I'll put an unmodified selector into the gun and weld it permanently in semi position. The trick to the narrow slot is to prevent the trip lever from ever bypassing the sear bent on the bolt.

The reason I mentioned it is that the selector switch slot gives additional support to the the trip lever and helps keep it in the right place. ( I know you already know that ) I thought about doing this mod myself but decided against it because of the above and also as I think it makes it easier to make full auto. I will not post the details here.

No problem Mick, I think you are referring to someone welding material back onto the selector to make it function again, but you would also have to mill or file out the slot to allow transverse tripping lever travel. To my mind, this would entail significant modification - but I don't know how the CFO feels about it yet. I will probably do the welded-in block mod to compliment this setup and make it even harder to modify.
