woohoo! i got my motor mount finished today. went into shop and finished up work on it with CNC friend. turned out sweet. i made 3 of them so i have 2 extra. if anyone is interested in one pm me for pricing.

so here are some pics. let me explain a couple of things first. the notch on one side of the face of the motor was necessary to give enough clearance for the center diff outdrive cup. i couldve done the part without the notch but that would have limited gear selection.

the reamed out insidea area of the mount is in 3 steps. first outer width fits perfect around the fins of the motor, 2nd width fits snug over the screws that hold that front endbell on, and the 3rd width fits snugly around the face of the motor which is the smallest diameter. fits like a glove.

the motor mount will sit on 1" wide x 2.5" long x 3/16" thick plates that will allow the motor to slide 3/4" side to side to adjust for gear selection and mesh. this allows me to go from 12t to as high as like 20t pinion gear. the plates didnt get done today but will be done tomorrow.

i got the 40t spur machined and its in the pics. still needs to be hardened though.

anyway, i am really happy with how the mount turned out. it will be mounted using 5mm screws throughout. there are no holes in the top of the mount yet for a fan since i have not recieved a 60mm fan. i willl just drill and tap those myself.
