Being a turkey hunter, I wanted to create a remote controlled, rotating turkey decoy that could house my GoPro camera. I needed a low RPM, high-torque motor but the one that I chose was very long (tall). So instead of mounting it vertically, I decided to build a 90 degree gear box to transfer the rotation to a vertical shaft. I found these Bevel Gears and modified them...I also added my own box and cradle to hold the motor. See video below.

I keyed the gear to match the motor shaft. The motor I used is here - http://www.amazon.com/gp/product/B00NN3JHIM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
