I used the XL series, .375 belt width, 20 tooth on ER16 spindle and 40 tooth on the Consew. Depending on your mount, 3.75-4.25" center to center. Just use the calculator above to get the part numbers.
Ton of Consew and Taig info on the Taig Facebook group.
Doyou think I can use this one and drill out the center holes in order to have it to fit the shafts on the spindles. Or maybe grind down the diameters on the shafts?
