Two month catch-up

So, we actually achieved some huge hurtles in the past two months.

For starters, Bill hooked up the high voltage electrical system. It was relatively easy with the directions supplied by our controller manufacturer Kelly. However, our initial high voltage test on the motor was problematic. The motor has no limiting factor and goes from O rpm to 5000 rpm instantly. All components are hooked up correctly (we think), but we could not figure out our problem. Bill has contacted Kelly several times, however, they have not given him a definitive answer to the problem. Our main objective was to get the motor spinning at a low rpm, so we could balance the coupling and transmission on top for alignment. We ended up using one low 6 V battery which spun the motor to suit our needs. From there, we stood the motor upright, and placed the transmission on top with the spacer plates between them to mark holes to be drilled into the transmission bell housing spacer plate.

The transmission and motor have been successfully mated together. We have four 2 1/2" bolts going through the 1/2" transmission bell housing spacer plate, through the three 1/2" aluminum spacer plates, and into the motor.

A few odds and ends include cutting the keys for the motor and transmission couplers. Bill's welder came over on Friday and put a bead of weld on the transmission spline so the coupler would not move depth wise.
