Did you consider milling cooling grooves in the CIM-U-LATOR instead of using spacers?

Yes, I just got the 9mm ball end mill to di this, but meanwhile we switched over to using the single motor version of the CIM-U-lator with the 18V 775 motor.
Distance is not quite as good, but it seems to bedoing better at handling force on the pinion bearing end of the motor. We can also boost RPM 7% by going from 30-to-30 with the belt pulleys to 30-to-28.

Thanks.
