Re: Using timing belts horizontally

I don't think so. I'd have to get them the next time I'm in the shop (the best part of a week).

BUT! of the three belts on any one of the machines they're on, 2 are horizontal (the third is on horizontal axles) and only one of those is a continuous belt. That one has a slidable tensioner--set and forget--and is used to drive a pair of leadscrews. I've seen minor stretch and occasional loosening. The non-continuous belts are tensioned by pulling more of the belt through the clamps that hold it in place.

For the application, I need them that tight--they're being driven by a trio of stepper motors, and need accuracy as tight as possible. But with them a little bit slacker, I can still get acceptable results. An FRC robot could go slacker still, but not by much.
