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 BLACK+DECKER DS321 was our preferred 3 x 21 Inch Belt Sanders. That doesn't mean there aren't several other really great options when it comes to 3 x 21 Inch Belt Sanders. We have a breakdown of them here.

Next up is built by WEN known to be a very respectable tool brand. WEN's Belt Sanders are great as well. I was eager to try the model 6321 and I was not disappointed!

This Belt Sander is just $43.18. That is a great deal for a superior Sander like the 6321 by WEN. The WEN 6321 is really a sound alternative. Of you are uncertain about our number one selection, I would select this Sander.

The 9903 by Makita and the PORTER-CABLE 352VS are worthy of looking into also. Both tool brands are well known for their high quality Sanders. both of these distinct tools received terrific user reviews as well. The Makita received a score of 4.6/5 as contrasted against the 4.0/5 star rating for the PORTER-CABLE 352VS.

The Makita 9903 offers several very premium features like Powerful 8.8 AMP motor; only 85dB. The 352VS by PORTER-CABLE although, is very competitive featuring 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.

Both of these two options are a great option if you're in the market 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.
