Double acting single set trigger model

[Scota4570]

I made a model of a single set trigger out of wood and nails.  The mainspring on the real trigger would be a cut out type the secures to the rear to make room for the lock bolt. I doubt I reinvented anything. It looks like it will work to me.  What do you think.

Scota, it looks like it will work very well.  Yes, you will be playing a bit with the camming surfaces, but that's just the nature of a project like this.
Making that wood model was a cracker-jack idea - works out a lot of the kinks.  Good luck with it, and make an extra for me.  LOL!
