Apologies for missing this forum. I mentioned this problem as a new item under "tooling forum." I have a Bauer 4 x 24 belt sander which is powerful, but whose speed control is erratic, wanting to race when put in the lowest speed setting ("1" on the dial). This is my third try at an HF belt sander. A year ago I had a similar problem with their 4 x 24 belt sander and returned 2 of them. I noticed that sander model disappeared completely. This sander seems identical under another brand name. Harbor Freight refuses to publish my critical 3 star , recommend buy, review, as "offensive". I kept the unit for its apparent power. At $99 it still may be worth it. I should have kept its sibling last year which was around $69.
