Following up on a request from YouTube, a clean look at the trigger/stock profile. Unfortunately I don’t have the complete blueprints, as I sketched an overall profile and then used paper cutouts to fine-tune the dimensions of different components.
The sketch in the lower left corner shows off the different components of the loader-trigger mechanism, although the final shape and size of each piece was tweaked by hand.
^Early fit check on a design with rather janky kinematics…
