This video helped me make a new trigger spring for my Suomi. It broke and spare parts are not easy to find. I used a high quality hair pin to make the new trigger spring, bent it and shaped it like the original spring. It worked, but I was lucky enough to find a new original spring. The trigger spring is the weakest point of this gun. There is not much else that can break, everything else is very robust. But the trigger spring is very tiny, it almost looks like a small safety pin. Every time you pull the trigger or pull the bolt back, the tiny spring bends. Over time it gets weaker. And if you are unlucky it snaps in half, leaving the gun useless until you get a new spring. My Soumi is an early production gun, from the first year 1931. So the spring survived a long time. But of course, there is no way of knowing if it has been replaced earlier or not.
Ah yes, PERKELE!
Anyone have dimensions for mainspring ? Outside diameter, wire thickness, pitch (=coil count) and free length ?
The trigger system is simple. Owen rifle also
can you explain how the trigger system works?
