Here is a picture of the final configuration ofthe motor and base for the working tank commanders.

The 58:1 gear head motor is held in place by a brass clamp made from brass strip. For the base I used a beadboard from Radio Shack. The two small white bits are tube styrene I threaded to connect the motor to the base.Threaded brass rod supports ca be seen also.

At the top you can see howthe figure and the motor will be joined. Two Du-Bro collar wheels soldered together. Under the lower collar Iplaced a small bushing made from brass stock. This helps keep the motor centered.

On the collars you can see the rare earth magnet that was CA'd toa small bit of brass rod. A hole was drilled and the rod soldered into the collar. This magnet is used to activate the reed switches. Inthepicture there is only one visible. These switches start the figure moving and then activate a relay that causes the figure to reverse, and finally stop.

Enjoy!
