We cut 2 test items on our router that felt really nice on the belt by hand, and the full set is being cut on a production cnc so I can only a high quality.
We cut off of the sdp-si CAD.

We did the same thing with a few pulleys, looked pretty close. A Gates Rep said SDP-SI pays them to use their formula. So I figure the model should be super close? Maybe?

I would still use a tension system only because it makes mounting much easier. I used sdp-si for all my designs my only negative is sometimes they are out of stock for belts sprockets and can take quite some time for you to get your parts, and that would be horrible if it was in the middle of the build season . Just got to be sure that you have a good selection of sprockets in stock or modify your design for what is in stock.
Just out of curiosity what width belts does every one use, I see alot of 3/8 inch belt out there. But I think you could probably go smaller without the fear of breaking a belt.

For GT2 5mm, common widths are 9mm and 15mm. We plan to use a lot of 9mm for all our non drive items. Rollers/Conveyors/Grippers etc... For Drive, 15mm would be pretty safe, but I bet you can probably get away with 9mm.
Adam can comment on the other smaller pitches of GT2: 2mm and 3mm. I believe the widths are a lot smaller?
