Chapter 2, Fabricate face and rear motor mounts

I then decided that the best option to mount the motor would adding two plates to the swing-arm mount.  Using cardboard I mocked up where the motor would be sitting and made templates. I was sure to include the chain tensioner and spring mounts (see next chapter) I then cut them out with cheap 1/4″ thick particle board to ensure all was correct.

Best picture I have of the swing-arm bracket. Also the ME1003 DC motor sits on a jack in position.

Wood motor mount installed, note how it overlaps the existing swing-arm mount.

Using a jigsaw, patience, clamps, and a hole-saw I cut the mount out!

Wood -> Aluminum

I then had to drill large 3/8″ holes through the frame and long bolts for extra stability and structure that the engine previously provided.

Note the 10" long allen bolts with 2" aluminum spacers for proper alignment of the mount.

Here is the REAR motor mount. It is basically the same as the front mount but cradles the motor with a high temp rubber edge, and a high strength hose clamp to ensure it engages and seats in the mount via wrapping around a stud at the apex of the cradle.

see how the mount cradles the outer permitter of the motor keeping it stable.

Top is the rear motor mount, bottom is the front (motor face) mount. Small triangle is chain tensioner (chapter 3) large triangle is battery mount.
