More Motor Mount Making

Steve, Clay, Brad, Jason, Moose, and I continued or work to make the modified Dan Baker motor mount/ankle sets. Steve setup the metal lathe and we collectively drilled pilot holes in each side of the metal spacers. After that was done, Steve changed the lathe around and we drilled out about half of the spacers to the exact bolt depth we need. On the next build night we will have to drilling the rest of the holes and tap the spacers.


Brad and I had to increase the hole that the motor slides into by using a router bit. We got almost have of the motor holes drilled before the bit snapped and Jason ran to the store to buy a new one.


After the holes where routed out, Clay uses the drill press and a sander attachment to smooth out the edges left by the router.


Steve and Moose setup the bending brake I got from Harbor Freight and tested out the bending process on a set of motor mounts. It turns out you get what you pay for. The bending brake is not sturdy enough to make a consistent bend across the entire motor mount because we are using 5052 aluminum. Steve said he will weld steel plates onto his bending brake to strengthen it and we will try again at the next build day.


Even though we need to fix the bends on these motor mount/ankle pieces, we placed a motor, wheel, and belt inside the mount to see how it fit.
