Topic tags/keywords: question sanding

I have come into some 3 1/2 inch by 72 inch 60 grit sanding belts. I could use them if I were to cut them in half (lengthwise) and tape the ends together. Then I would have two sanding belts. My problem is that I don’t know the procedure it takes to keep the loop. Now the question… Do any of you LJs out there have any experience in making your own sanding belts? If so, might I glean some advice on procedure? Taping, gluing, clamping? Thank you in advance for any help in this matter.

I am curious about this as well.

I did find a method for making stroke sander belts written
in a very old article by A.W. Marlowe which involved 2 layers
of linen strips, glue and temporary nails driven into a block to
keep the belt straight

I contacted a sanding belt manufacturer a while back and asked what type of adhesive they used. They told me the adhesive used was propriatary. I tried various industrial adhesives and tapes, but nothing worked.

I’ve dug a bit deeper and I think it’s generally done with
the tape applied with a special heat press.

A guy on some machinest forum said belts could be
made-up or repaired using book binding tape called
“Accubind” and a kitchen hot bag sealer to press
the tape into the belt under heat.

Hide glue may be a viable option though, because it
retains stickiness on a molecular level even when it’s
all broken up into tiny crystals, which is why it was
used on organ and blacksmith bellows and hold old
books together too. Whether it can take the heat
buildup in your sanding application is another matter.

I haven’t tried it yet but this guy posted his method for making belts on YouTube.

Call someone like 3M and take adhesives with them. They have an engineering dept. that will take with you and they make everything. Maybe you can learn something to teach us. Good luck.

Carpet tape and an iron?

Thanks L.J.ers for your replies and advice. Sorry for the delay in my response, but Labor Day weekend and all that goes with it. First stop would be the Post Office. Path of least resistance. Then if needed and maybe anyway, a couple of phone calls. I will report back with my findings.

Play safe,

Ok, I’m back. I can’t believe it took this long. I went to the Post Office and got the packing tape with the fiberglass cords running through it. The first one I did up I just taped and put on the belt sander. It fell apart in seconds.

This is what I started with – cut open 72” X 3” sanding belt.

I then cleaned off the original tape and sanded

Applied new tape then ironed with wax paper under and over the sanding belt. Don’t iron too hot as I did with this one. I had to re tape and re iron.

After things cooled down, I ran a bead of super glue in the rock side seam after running it on the sander and seeing a little delamination as the seam traveled around the barrel of the sander.

I ran the belt on the sander for about five minutes while sanding down a piece of hard wood with good results. I don’t know as yet if this method would work in the long run. That’s what I have so far. If I have trouble too soon I guess I will have to make some phone calls.

The carpet tape sounds like the closest thing to what I’ve seen on how they attach the ends. That combined with some clamping force should make for a pretty good bond. The trick is making sure when the belt is in use that it never gets to the melting temperature of the adhesive or the results will be predictable.

Jay, Keep us posted as I have tried a lot of things that didn’t work! The strapping tape was a fail for me but I didn’t think about ironing it.

3M makes a tape called VHB (Very High Bond). It uses an acrylic adhesive. I t was demonstrated that a locomotive could pull another loco coupled together with VHB tape. There are some demonstrations on U-tube.
