Thanks for posting the links Eddy as I was looking for them, what's the smallest number of teeth to use on the pulleys to be safe ? I've read some where with a small number of teeth there's more chance for the belt to jump the teeth and cause problems with racking.

6 teeth in mesh is minimum for all pulleys. Means all specs on the sheets are for that particular case.

The best belt calculator i have found

thanks :) found just what i needed :)
