I have two questions about belts.
1) Given the contraptor 10 tooth pulleys, is the the forumla to get from shaft distance to belt size [Shaft Distance" * 2] + 2" = belt size. So if you need 100 inches between your shafts, then the belt size is XL202? Or if you want 30" between shafts, then it's XL600? Does this seem right?
2) Is buying a bunch of open ended belt a good idea? Then we could support any contraptor shaft distance. I was thinking of this since belt sizes are not all even. At least with SPI and McMaster, not all shaft sizes (ones that are contraptor compatible) are supported.
