    I had a need for a pipe sander for a 6" X 35" column I am making but the price was way over my budget.
    So I went to HF and Lowes and for $15.95 made my own and it really works great.

    That's pretty spiffy, Ray.

    I presume that the white pulleys are Delrin (acetal). Can you provide the dimensions and the bearing numbers? I have recently had a need for something very similar recently. Good job, especially the price.

    A neat solution to your problem. I'll have to file that one away for future reference!

    The grinder is from HF $9.95 and the sanding belts are from Lowes 1"X42" $5.95 for package of three. The rest of the materials I had in the shop. The plastic is a mystery material but probably acetal. The grinder turns 11,000 rpms so I made the drive pulley the smallest diameter I could safely get away with to lower the belt speed. I drilled and taped the grinder output shaft 1/4 X 20 to attach the drive pulley. The idler pulleys are a little larger with sealed ball bearings but the size is not critical. I thought I may have problems with the belt tracking properly but that is not an issue and the geometry can be quite a bit off before there is a problem.

    Thanks all

    Ray

    Thanks Ray, I will surely be putting one of these together. I have some acetal and have been looking for a small project to see how it turns. John W

    Good job. Buy the harbor freight router speed control and you'll have variable speed.

    I wish I had seen this some years ago when I wanted a very narrow belt sander.
    Nice job.
    On an aside I wanted to sand the outside of some thin steel tubes so I flipped one of those belts inside out so the grit was on the inside, held the tube in the vice, used a skateboard wheel tight in the drill and placed it inside the belt loop, pulled tight and turned on.
    It took a couple of goes to get the hang of the angles and belt tension but I was soon ripping paint, smoothing welds and the belt contoured around the tube.

    I will have to try that but I am a little concerned that the power will drop off quickly with the speed reduction.

    Thanks All

    Terrific idea, simple and inexpensive. Could think of a lot of uses for that.

    I've been looking at these. The new cheap chinese ones at $~175 are within reach, but I also thought about building one. Didi you make any drawings you might care to share?

    Nice... I'm visualizing a smaller version, perhaps with a Dremel motor...

    Why three wheels?

    That was design #1 and design #3 is much shorter and somewhat different.
    The third wheel pivots so that the sanding belt can wrap around the material as it works.
    I do intend to make the plans available in the future but sure when.
    Thanks
