Turn it upside down and put it in between two 2 by 4's. But at the end of the day I'd take a good look at the BLACK+DECKER. Makes me wonder why all belt sanders aren't made similarly.

I give it four stars because I have only had it for four days. The variable speed is amazing for the serious wood worker. We restore 4-6 pieces of furniture a year here at the house. Also take a short break every 15 minutes to let belt cool off. And that was with the 80 grit sanding belt that comes with it.

The fact is that the BLACK+DECKER DS321 was the 3 x 21 Inch Belt Sanders that we ranked most highly. However, there were several other truly high quality 3 x 21 Inch Belt Sanders worth showcasing here that just barely missed first place.

WEN is another leading manufacturer of Sanders. They produce the tool next on our list. WEN's Belt Sanders are no exception. It was terrific to test the 6321. I was very pleased with this tool!

The model 6321 Belt Sander by WEN, at $43.18 is an especially excellent Sander for the money. If you uncertain about our top selection, I'd consider the WEN 6321 next. It's a first class tool at a terrific price.

Besides the selections we already included, I would definitely evaluate the Makita 9903 and the 352VS by PORTER-CABLE. Both tool manufacturers are known for their high quality Sanders. Both of these two options are rated highly also. Customers awarded the 9903 an average score of 4.6/5 stars. You can liken that to the 352VS that boasts an average score of 4.0/5 stars.

The Makita 9903 offers several really choice features like Powerful 8.8 AMP motor; only 85dB. The PORTER-CABLE 352VS by comparison, is very competitive with Variable-speed belt sander with cloth dust bag; variable-speed dial 850-1,300 SFPM plus Belt and gear drive system transfers power from the motor to the sanding belt.

Each of these two choices are an excellent decision if you're shopping for 3 x 21 Inch Belt Sanders

I just bought a house and it needed to be redo my back patio. For the price, all things considered, this is a good value. I am a finish carpenter and use my sanders constantly. If I had to choose one I'd take the Makita over this model. Great value vs similar, more expensive belt sanders.

It is very maneuverable and the dust catcher works great also. The brushes are replaceable in the event that they wear out. All the others died completely after about a floor and a half. I will have no problem buying from this seller again! Pair with the new 9ah batteries it's well worth the money.

I got some replacements and within a week they were arcing. He must be happy for he has been in the shop for hours! It's light, easy to hold, and gets into tight corners. I use it a lot for flattening hardwood panels after glue up. I've since used it myself and was please what it could do.
