This struck my interest as I deal with a lot of timing belts at work. There are some rarer trapezoidal profile with 5mm pitch. I just looked at my little 7x lathe and it has the same belt ( 1.5x70 ). I'm not going to be using my lathe until the weather turns, so tomorrow night I'll pull the belt and pulleys to take into work to really investigate.
