Query: 4 x 24 belt sander

Out of the box ........good balance and good access for dust collection, but I noted after several moments of use that the front idler (for the sanding belt) was significantly out of round. The unit wobbled noticeably and sanded accordingly. I called their service # and after 3 tries with different people found someone who thought they understood the problem. Initially they recommended my taking it to a service center......but I refused and instead asked for a replacement idler, which they agreed to. The first box sent contained a drive belt???? Not sure how that was arrived at. Another series of calls eventually produced the correct part. I changed out the idler and the unit now works fine. The defective idler appears to have been cast but never turned or trued up. Too bad something simple casts a negative shadow on a otherwise good tool.Rosewood
