CIM motor with 12 tooth pinion to 48 tooth gear on the first stage. 20 tooth to 36 tooth on the second stage. 20 tooth to 35 tooth AndyMark Dog gear on the third stage. The third stage uses the AndyMark long shifter shaft and a custom made spool which winds up the nylon strap pulling back the "piston". Attach a bunch of surgical tubing to the piston base and the front of the launcher and there you go. Our next version is redesigned so it uses a minicim and a GEM500 gearbox in conjunction with the dog shifter/spool assembly so as to simplify the gearing. It will also include a sled launching approach, instead of at the end of a piston. Hopefully it works just as well, if not better.
