>>Yamavolt project: Motor mount mockup

The D&D golf cart motor arrived this week, along with the Alltrax controller. The motor weighs 38 lb. I cut a cardboard pattern for a set of motor mounts, transferred the shape to half-inch plywood, and bolted it up. Here’s what it looks like: nice, tidy package.

The next step is to duplicate the mounts in hard aluminum sheet, and get some chain sprockets made up. I’ll use 84 teeth on the rear wheel, which has an odd four-bolt hub-mounting pattern. The front sprocket goes on a 7/8-inch shaft with a keyway. I’ll use a 12-tooth sprocket to start, which ought to give me 49 mph at 4800 rpm — if the motor will pull it.

Still waiting on the Magura throttle, and I’ll start scrounging for batteries this week. Another project is programming the controller, so I’ll spend an evening figuring that out.
