Motor and Wheels – Attempt #1

August 10, 2013

Hi, I’m back again with details of the motor mounting and wheel attachment. 

Be sure to use Loctite™ or your favorite thread locker as the vibration and jerks can be severe and will loosen anything that is not secured well! The voice of experience speaks!

This is the basic Motor Stripped out of the case, The chuck removed and clutch locked.
The motor has 1 3/8-24 thread. This is uncommon as most bolts are 3/8-16. So I made an adaptor that also functions as the axel. I used a 3/8-24 nut, a 3/8-1/2 sleeve 1 1/4″ long, and a 3/8-16 nut. Assemble these. Use Loctite™ to lock the 3/8-24 nut in place. Drill the motor shaft for a locking screw (#8 or #10 is good). Insert the 3″ 3/8-16 threaded rod and drill for a similar lock bolts. Add the 3/8-24 jam nut (Don’t forget the Loctite™!)
This is how the wheels are mounted.
Nut, fender washer, rubber washer, sleeve, place wheel over sleeve, rubber washer, fender washer, (Loctite™) nut.
The rubber washers are an attempt to isolate vibrations. Only time will tell.
Note the toy car tire on motor. This will go under the hose clamps

Motor and wheels mounted on Base using hose clamps. Later I will use 3D printed Motor Mounts.
I used some old toy car tires that happened to fit as isolation/motor mounts under the rear clamps. This should keep it from slipping out or twisting.
