For some reason I’ve been playing around with our LEGO Technics quite a bit lately and built a bunch of different rubberband guns over the past few days. The one above was a good attempt, but them I started getting a little crazy with gear reduction.
Version 3.0
This one has a firing ratio of 4/3 (20 positions on loading gear, 15 trigger pulls for 1 complete revolution)
Version 4.0
This gun has a firing ratio of 8/9 (8 positions on the loading gear, 9 trigger pulls for 1 revolution)
Version 5.0
Finally, this one has a firing ratio of 1/1, though it took an excessive amount of gearing to get there.

Interesting that I was looking for cartoon gnomes and found this! My buddy and I just built the Parabella gun from the Badass Lego Guns book. We’ve been working on modifying them too. Very cool designs you have here! I like the trigger mechanism (pull – release) and how it interacts with the letting go of the rubber bands through a gear reduction.
