Semi-automatic: trigger mechanism...

I thought I would start with the most complex mechanical part, i.e. the trigger. The mechanical idea for this gun is not original. It was inspired by guns I have seen in the past that made me want one to begin with. Below was my first go.



It didn't work at all! I decided to completely redesign it. Below was my second go. It isn't perfect, but it works.



It is functional, but it isn't smooth. Still, I think I want to move on to other areas of the gun. The next challenge will be designing the barrel and handle in such a way as to snap together in some way. I realize nuts and bolts are cheap, but I welcome the added challenge of making them unnecessary in the design.

As this is a mechanical project (read moving parts) I thought it would be appropriate to include a short video of my second attempt.
