About this 3D model

As I finished modeling the Fairbanks-Morse hit and miss engine, http://www.thingiverse.com/thing:113398, I kept thinking it should be running. The 1/16 scale model is surely big enough to house a small electric motor and a battery pack. So back to the drawing board (or is that the “CAD Pad”?) See it run at: http://youtu.be/0-gTHz5ukeY Well, it is still a tight fit. The motor must be mounted normal to the flywheel axis. So we need bevel gears to couple the motor with the flywheel. I hollowed out the gear box, and gave it a separate, glue on cover. Separated the base and found room to install the switch and battery back. Now the engine is just looking for something neat to power!!!
