Use a motorcycle jig design that comes with instruction and specs so you can complete your task with relative ease.

Ensure that your axle plates are positioned correctly. You should use shaft collars and pacers between the plates. After positioning the plates, weld a ½ inch steel plate into a ½ inch square tube. Drill holes and insert bolts into the holes to have space between the plates.

When you have completed the axle post, you can start on the engine fixture. Begin by putting the two lower rails together. Use a bolt to fasten the rails securely. Use four setscrew jacks to secure the fixture and the engine plate. Attach your jacks at the corners of the plate. Drill holes for setscrews to secure the parts of the motorcycle screws. These are used to secure the engine plate and the rails to the motorcycle. After the engine fixture is all done, make sure that all of the parts are functioning properly.
