Looks good. Can you tell me the approximate diameter of the arm on the motor and how did you build it up to the 2 3/8" ID of the primestar mount? Thanks.
Start with a piece of 2in PVC pipe, cut it to the length of the straight part of the motor tube then make two lengthwise cuts to remove about 1/2in from one side so its like a C. This is for relief of the PVC as its compressed around the motor tube and also to make your life easier with the assembly.
