Hey Dowling...
Plywood... for boats?.. from the lenght of the belt.. I assume it's for the X Axis.... how are you driving it?...
Pitch... you wouldn't want anything less than 10mm. $85.00 sounds reasonable. Maybe a T10 or a T5.
3/8 pitch?... suitable?.. depends on the size of your pulleys... on a large pulley... 300mm +.. that would be fine... you need to ensure that there are sufficient teeth on the pulley when mounted... there is a formulae.. can't remeber... something like 40% of the teeth engaged?.... if your pulley is too small for the belt then the teeth won't engae properly.. when you use smaller pulleys like on the Z axis a good pitch is 5mm...
hope that helps
cheers |
