Make a flap sander w/ recycled sanding belts

First, I know this isn’t a finished woodworking project. If it offends the webmaster at Lumberjocks, please move it to whatever category makes you happy. I was not able to add the photos in the blog section. Why not allow woodworkers to share their creative techniques and ideas with one another? That is one of my favorite parts of this site.

That being said. Here is a simple sanding mop or “flap sander” that I made using recycled 4×36 sanding belts. I cut them into 1.5” x 6” strips and punched a 3/8” hole in the middle. Make a series of 2” deep cuts to feather the ends and mount onto a 3/8” carriage bolt. Alternate the grit, facing up/down, with each layer. Use fender washers on top and bottom and lock everything down with a nut. It works great on contoured workpieces like mirrors, canes, etc. Rockler.com carries a similar 6” diameter model for $50. Mine cost about 50 cents!

P.S. I should’ve mentioned in my write-up, that it’s a good idea to wear safety glasses while you operate this. Even though the cloth-backed sandpaper is very durable, “better to be safe than sorry.”

I paid even more at a woodworking show than Rockler charges , but that was a few years ago.
I won’t do it again after seeing your great job with this one : )
Thanks for sharing it with us !

That’s a good idea.
I’ve got old sanding belts lying around because I don’t throw away very much.
I definitely could use this in the router bowls I make.
Thanks for sharing this.
Also, I saved the pictures on my computer in case the webmaster takes this down for not being a woodworking project. I guess it should have went in your blog. But, I too have problems uploading pictures in my blogs. But, only from Photobucket. I just upload pictures from my computer through the “img” button.

This is a great way to recycle a dozen or so of those odd sized sanding belts I picked up in a yard sale. Thanks for defying the web gods and sharing your idea with us. I also ran into the same problem. I couldn’t upload pictures to make a blog, and I have no plans on joining any photo storing/sharing web site … so no stick straightening blog.

I too wanted one of these but couldn’t find the bucks yet. Now I can copy you! What did you use to cut these strips with? I would think a utility knife would dull very quickly. Great Post!

This is brilliant! Thanks for sharing. I’m also copying and pasting the entire thing into a word document just in case it gets lost. This is just great and will help me keep on woodworking on my nonexistent budget!

Ivan, I made one similar to this and used the $19.95 Paper Cutter from Harbor Freight. I originally bought it to cut sheets of sand paper into quarter and half sheets for my electric sanders. I’ve been using it for years and it still cuts sand paper very well.

Thanks, everyone for your nice comments. And, thanks Thelt, for the suggestion on the paper cutter. I just used an old pair of scissors, which worked fine.

I should’ve mentioned in my write-up, that it’s a good idea to wear safety glasses while you operate this. Even though the cloth-backed sandpaper is very durable, better to be safe than sorry. In fact, I think I’ll add this paragraph…
