Thickness of the Gates Blue T104RB excluding tooth height is averaging 2.35 - 2.40mm measuread at various points around the belt and on both sides. I will be able to measure a Gates HSN and JHPS belt tomorrow.Did you ever measure the Gates HSN & JPS belts? I just measured a new Flennor 24513311 black belt, and two other used belts I couldn't identify, and the readings were all 0.088-0.089 inch (2.235-2.261 mm). That's about 0.004" / 0.1mm difference between the blue & black belts. Not as much as between the blue & black HTD belts.
Stretching my memory, but for the HTD belts, I think the difference was more like 0.016-0.015"), and that made about a 3-5 lb difference in Burroughs readings.
