So making a "slam-fire only" Roughcut isn't trivial like it was for the Rotofury. =(

My initial thought was to pretend the trigger was there and always pulled, by just popping out the spring (green arrow) and tying down the big white fork-shaped plunger catch piece with a twist tie (red arrow). Nope, bad idea. The plunger catch needs to be there... to catch the plungers.

The slam-fire magic happens because the "done priming detector" (blue arrow) slides BACKWARD while you're priming it, allowing the "floating block" (purple arrow) to move back and stay "up" to effectively IGNORE the trigger, leaving the plunger catch fork in its "up" position.

When the pump handle gets back to the front of the blaster, it drags the "done priming detector" forward with it, which does nothing if the trigger isn't pulled, but if the trigger IS pulled, it shoves the "floating block" against that angled part at the front of the trigger which forces the "floating block" downward.

This in turn pushes downward against the "lower deck" of the plunger catch fork, thereby releasing the plungers and BANG-BANG!
