Gene, If you need 380 mm, but 600 mm is the shortest generally available, is there room for a pair of idler pulleys off to the side, making the whole belt path resemble a boomerang? The boomerang arms would be significantly less than 15 cm (6") with 60 cm (2') belt length, so it wouldn't take up a lot of room. (The outer idler would be larger than the inner, to avoid belt fouling.) Might need a new belt cover if it's on top of the minimill, though. There's probably no belt length calculator for that scenario, but four cardboard wheels cut from a beer carton, and a bit of string, ought to suffice for non-computer modelling, I figure. If you find a good price on poly-v belts of either length, please post the link. It might help me start on a project still on the back burner. (There's a few of those.)
