Okay I finaly finished motorizing it! I bought the tamiya three speed gearbox. Cut an allen key and filed it to the diameter of the smaller hexagonal axel (easier said than done with hardened steel!). I cut the box's empty chamber to allow the axel to mesh with the main winding wheel, and am using three 4.5v in total AA batteries to power it. I use the largest gear ratio like you recommended but it just wouldnt wind the mag fully even with the 9v i was testing it with, and the mid gearing has the axel in the middle so space constrainst prevented that. I ended up using low gearing/high torque and it winds pretty darn fast! (faster than people can work the wheel thats for sure!) and doesnt put unnecisary stress on the motor. Popped a pressure switch into the circuit and good to go! johyew my friend you deserve a medal! you saved me so much time and trouble and the gearbox fits perfectly just foam to keep things secure and silent and it mounts right in!
ps your my hero *star*
Peace!
