Yep, the end is near. 
We're getting into an area where my experience is not as great as the electronic arena, and I don't have the proper tools I suspect. I'm hoping I could pull the gear off the set motor and get it onto a larger motor for better power.
I suspect that I'd be using something like the Loctite 380 Retaining Compound to secure it. It is also a gap filler that will allow a bit of tolerance for the size of the drill (I hope).
LOCTITE® 680™ Retaining Compound High Strength/High Viscosity is a high strength, high viscosity room temperature curing adhesive used to join fitted cylindrical parts. It fixtures in 10 minutes and provides a shear strength of 4,000 psi. Capable of filling diametral gaps up to 0.015 in. (0.38 mm).
LOCTITE 680 allows relaxed machining tolerances, and replaces clamp rings, set screws, and snap rings. Gives best resistance to dynamic, axial and radial loads. Recommended for retaining shafts, gears, pulleys and similar cylindrical parts. NSF/ANSI 61 Certified. ABS Approved.
This should keep the gear where it needs to be if I can get the correct sized hole in it.
