Thanks for the info on the belts. Where do you buy the Klingspor belts? Also, I've been using 100 grit belts to finish my timbers. It seems to look alright. Do you (or anyone else) recommend a finer grit. I don't have two large belt sanders (one for coarse grit and one for fine), and really don't want to sand twice anyway, that's why I initially went with 100 grit. Comments anyone......
