Building my own rear axle.
I am making a chain drive differential using parts from an MX5. I cut off the rear axle plates and drew up new plates in CAD to mount the pillow block bearings. I will have 3/8" steel waterjetted once I finalize the design. I had to cut and bend the top tubes of the rear hardtail for the body to fit, since it was originally designed for a flathead Servi-car. The new steel plates will extend under my cuts to make it strong.This thing is EXACTLY the right width for the HD frame. I have a 1" keyed axle to make the left and right axle shafts, and a couple of 1" pillowblocks for near the wheels. I will need to make upper and lower tubes to support the bearings at the wheels, leading back to the seat post tube. I think the rear diff and output shafts were about $150, $50 for the bearings, $200 for the axle and hubs. The brakes are from a Polaris RZR, rotors and calipers for forty five bucks, can't get much cheaper than that. DNA sells a trike axle for a couple grand, but I did not want disk brakes visible, to me it kills the look. I'll have maybe $500 in this setup. -
