PPSh-41: Trigger Assembly
The front sight came together very fast (about 1 hour) so I forgot to take pictures along the way. I didn't have any good reference for the sight post so I modeled it after the front sight off the AK-47. It isn't glued in so when I get better photos, I can change it. The flat part is laminated styrene with a hole drilled for the post. The Ring was heated plastic stretched around a bottle. The "feet" were created separately because any applied heat would ruin the ring.
The extractor sits in front of the bolt and strips the expended casing out of the bolt face. A little glue and some filing for this simple part.
The selector switch (allowing either semi or full-auto fire) was a bit of a mystery for me. All I had to go by were some long shots and a cutaway drawing. Assembled I think its close...the actual construction is my best guess.
The trigger assembly involved much trial and error. I barely understand the mechanisms but everything seems to work!
