At the end of the last piece on the MP28, I was doing battle with the fire select mechanism. I found a solution in cutting off the automatic mode altogether, not just one of the wires. Below is my original (functional) test rig.
And built into a usable switch.
This can be mounted into the Sten body with a screw. I have placed it at the back of the operation handle channel where it will be both accessible and discrete.
One oil finished knob later and the fire select is complete. You’ll note the rather ugly M6 screw which is temporarily filling the role of op handle until one is made.
Next job is to replace the trigger. The original was too short once it was set into the wooden stock. I simply cut around the top to keep the shape and improved the size and shape of the trigger blade itself.
I fitted the battery compartment cover, this gun will take LiPo batteries which keeps the battery compartment size down.
Closely fitting the buttplate before applying the finish to both parts.
Several coats of Danish oil darkened up the stock and brought out the natural colouring nicely.
I could then fit the oil blued buttplate with two oil-finished screws to blend in.
And apply several coats of a new finish I am experimenting with that should produce a hard, wear resistant and semi-gloss surface.

The extending wire that links the battery compartment to the mechanism.
Another view of the extending wire. The catch is screwed down with machine screws rather than woodscrews as it may need to be removed and this will reduce wear on the stock.
And finally… with the mechanism in place.
