Motor Mounts...

Angles from the frame to rear plates, slotted to allow tensioning the chain.  These slots go to the frame allowing front back tensioning.  They are 0.375" wide and 0.75" long.  They use the rear most unused holes in the frame that were used originally to hold the frame together when welding.

Angles in place to test fit & alignment.

Motor Plates mounted, at this point the angles also have horizontal slots where the motor plates can be shifted left right to allow the chain to track true.  All the hardware here is 0.25" the horizontal slots are also 0.75" long.  The plates are made from the 0.375" jig plate I mentioned in an earlier post.  The hardware into the motor gear box is M6 and I did need to replace what was there with longer ones to accomodate the plate thickness.

Next up is cutting and fixing the chains for the rear drive sprockets.  Happy Holidays.
