Step 6: Drive shafts

Picture of Drive shafts
I had to make some custom shafts to mount the wheels to. I was originally just going to modify some allen keys of the right size but I ended up getting some 5/16" stainless steel hex bar. I turned the end down in my lathe and cut 1/4-20 threads on the end. Screws on both sides of the motor keep the shaft from moving out of place.
