I'd like to make a suggestion on the design of the trigger wheel...
The current design shown in the pics makes the trigger wheel kinda delicate?
The "fins" could get bent due to debris being kicked up into the wheel?
I would run an "outer ring" just to "protect" the fins from getting bent.
Bent is bad, right?
This might increase the price of production due to the fact that (laser) cutters don't like to start and stop during each piece.
