Tiny Gear Puller Sure we could buy it for a few bucks but what fun would that be!
After almost destroying my Hacker Brushless motor (used on my Hornet 2 heli) trying to pull the gear off, I got smart. I made a dedicated gear puller. It's wonderful and works with ease! You can also buy one from GWS for about $10 bucks, and I highly recommend it.
Mine is, in general, a copy of theirs :)
Time, about 45 min.

I first milled a rectangle using 6061 aluminum. I followed up with a pocket and milled a slot though the piece.
Here you can see the hole that was drilled and tapped for a 3 mm Allen screw. The end of the screw was turned to 1.60 mm
Here is the other side of the piece. After I tapped the hole I mounted it (using the tap as a mandrel) and turned the piece.
Here is an assembled view with the slot rounded off
Works great! Now I can keep from destroying my motors :)
