Re: How to figure out belt lengths?

Well, plug in your numbers for pulley size and desired wheel spacing, and the calculator gives you the possible belt lengths. You are unlikely to get exactly what you desire for a spacing, but you'll have two options that are close.

In your case, your options are to use a 130 tooth belt at a spacing of 9.2529 or a 140 tooth belt at a spacing of 10.2372.

When you lay that out, you need to be fairly accurate, so I'd strongly recommend calipers, layout die, and a machinist's scale.
