However we used tube and CNC milled them, down to probably +/- .003 tolerances. We never had an single issue after 2 regional.

Very nice arrangement, we're working on something similar for an offseason project. Two questions:

1. Do you mean you milled the GT2 pulleys? If so, can you provide some details on what is required to do such a thing. Are there specific CAD tools, special cutting tools, etc that make life easier?
2. It sounds like you didn't have any issues with belts skipping/ratcheting, even though 15mm belt sounds like a "safer choice" for a drivetrain. Using the 9mm did you drive it hard, go from full forward to full reverse, push much, etc without issues?
