As you mighy recall, I have been planning to build the M4A3 (76mm) Sherman. Thankfully I found a book with a blueprint and a scaled ruler. The finished tank should be 1:6 scale, but much of the geometry will be simplified at first.
The question I have deals with the motors. I hoped not to use expencive motors for robotics, so I happen to have two reversable 12vdc drills which can be opened, creating a basically cylandrical engine about 9 inches long. Unfortunately, both motors, when set on one axis facing apart, their width exceeds the tank hull's width of 10 inches. The only other option I could think was setting both motors parallel inside the engine compartment and using two shafts and cogs to drive the front sprocket―very similar to the real Sherman's design. Does anybody know where I can look for small 90' cogs? I was hoping to use the drills' chuck clamps as a means to easily attach the shafts to the motors as well as make minor adjustments if necessary. Thanks, -Mike M.
