Thanks so much @gwilson (over on the Local Motors Projects website) for your help with the new aluminum motor brackets. Can't wait to finish those up and get the motors back on this bad boy.
Galen whipped together designs Saturday morning for new motor mounts made from aluminum to replace the old bulky wooden sleds I'd made in haste. Here are the waterjet-cut parts:
The back (non-sprocket-stickin'-out-of) side of each motor has a couple of bolt heads sticking out, so Galen designed one side of the motor bracket to go straight across the back. To make the Office Chairiot even faster, he added "speed holes:"
I think those add about 5 MPH to its top speed. We'll have to verify once I get the LCD on the control panel working again so we can see real speed data.
It might be a little difficult to see on a darker screen, but I added "wing walk" grippy self-adhesive pieces to the chassis where the motor mounts will sit to help lock the base plates of the mounts into place once the nuts are tightened.
Here's what the motor bracket piece of the mounts look like in semi-action:
The base plates will have a hinge feature to allow us to rotate the motors up and down to tension the drive chains. The hole at the "nose" of the brackets is for a bolt that will set the rotation of the motor and lock it. The plates will have matching slots to allow us to accurately align the sprockets of the motors and the wheels.
