Review: Worked flawless.... after small learning curve. - So first off. I've never used a belt sander before. In the pics this is a 30+ year old bench built by my grandfather. Just sitting on it and you got seven splinters. I decided to take apart, rebuild, and stain. So for the first run... belt was flying all over the place. Complete fail. However! You have to take time. Read instructions. Turn unit over, set, and adjust the dial. The dial adjustments are actually quite small. A quarter inch turn, turned out perfect. It is very important to get this set FIRST! After figuring this out was flawless. Ran like a champ. Removed dust bag as this volume of dust was ridiculous. Overall best idea ever, super affordable, and worked like a dream. Highly recommended. Just take the time and learn how to adjust the lock the belt. Cheers and good luck!
Review: Best belt sander I have ever owned. Issues in reviews are unfounded. - So I have owned many belt sanders in my day. In fact, I have 3 others presently when I decided to buy this one. The primary reason for this purchase was this sanders' large front space in front of the handle to be able to get under railings. My project is sanding a deck with existing vinyl railings that none of the other sanders could get under. So this seemed like a perfect solution. I got the sander and put it right to work. I paid attention to the front wheel and adjustment as many reviews here complained that it was badly engineered and the belt kept coming off. I completed about 150 feet of edging, under railings and along the house on this deck and the belt acted exactly as you would expect; if you push in one direction it will move in the opposite direction. In other words, if I am pushing down on the front of the machine and I slide the machine to the left, the belt will want to move to the right. It isn't an engineering issue, its physics. Anyway, great product. Did exactly what I wanted it to do and solved a great problem because of the unique design. Well done B&D.

## Questions & Answers

**Q: Sander keeps slipping. The sandpaper won't bit onto the wheel, wheel spins, sandpaper doesn't move. Just started happening recently.**
A: Two possibilities come to mind. 1. The lock on the side is no longer closing as tight as it should. I have found that sometimes when I close that lever, it doesn't go as far as it should. I have to push it in a bit further to seat it. 2. Try seating the sandpaper in as far as it will go laterally, lock the lever and try adjusting the tracking wheel back and forth. 3. Check the foot and see if it is smooth-nothing for the belt to catch on. Also check behind the drive wheel for anything clogging the exhaust port and catching the belt. If it's anything else, such as either of the wheels being worn, you will probably have to replace the sander--it ain't worth fixin'. Another thing  it could be is that the belt is sized incorrectly. Double check your belts and verify that they are 3x21. Hope this helps.

**Q: Is this tool variable speed?**
A: Don't need variable speed - it's a power sander.  Sounds like you want a hand sanding block so you can limit possible damage to your delicate work piece.

**Q: What grit should I use to sand glue from under a floor tile in the bathrooms to make it smooth?**
A: BEWARE !   Asbestos was used in flooring and adhesives up until the 1980's   You don't want to sand it if there is any  chance there is asbestos in it.   Another option that sometimes works is to get a bunch of kettles of water boiling,  and keep wetting it with boiling water, while simultaneously heating it with a heat gun.  Best to have a helper, so its easier to keep all of it both hot and wet.   Scrape it with a good flooring scraper.   Start in one spot,  and work your way out from it.   This method doesn't work with every floor,  you'll know within 20 minutes or so whether it will work for you.    To avoid asbestos dust the pros generally use floor leveler or emossing leveler instead of sanding.

**Q: Does it have a variable speed feature?**
A: No, there is no variable speed. Slow & steady.

### ⭐⭐⭐⭐ 4 star rating except....
*by R***R on May 22, 2023*

This is a nice little sander except for the engineering flaw where the the lock will not keep the sand paper in place on the belt. at least 1/4 the width of the sandpaper keeps slipping out to the side (other reviews have made this complaint as well), AND the dust collector system stopped working. It still worked, but it made the sandpaper wear unevenly and made sanding much more difficult and much less efficient that if this design flaw did not exist. It surprises me that engineers let such an obvious design flaw make its way into production. It would be a very nice little sander otherwise. This flas is irritating enough that I wish I would have purchased a different product and would not recommend this sander to anyone looking for a sander like this in this price rang. You can do better.
