I have a Performax 10-20 drum sander and I am having a problem with the sandpaper. I know the space to get to the sandpaper clamps is tight… even for my small hands. However I’m not sure that is the problem. I ripped 2 new pieces of sandpaper roll today while running some boards through the sander. I can’t tell if the paper is not tight enough, the drum is not parallel to the table (I can fix that but I’m not sure that is the problem) or if I’m doing something else wrong. The paper always rips at the right side about 1/2 to 1 inch from the clamp. I take very small bites with each pass. While at Rockler today, I noticed that the 16-32 now opens from the top instead of the front… no, a new drum sander is not a possibility at this time. I’m hoping that one of my fellow LJs might have an idea as to what I am doing wrong and, more importantly, what I can do to correct the problem. The rolls are pretty expensive to rip so quickly!!
Thanks in advance for any advice,
Ellen

Having a similar problem with the 16/32, I found that the paper has to be very tight on the drum and the end of the roll often is loose, or becomes loose after a few uses. Winde the paper as tight as you can and make the end clam as tight as you can then run it and check it again. Hope that will help. The sanding pulls on the roll and pulls it tighter to the drum making the end loose.

Have you made sure the rollers are absolutely clean when you install the SP? Just a thought

I have a different brand drum sander, but I used to have similar problems with mine. I would wind my sandpaper as tight as I could and I’d end up tearing a piece after using it for some time. I discovered that the heat of the sander was making the sanding strip get a little longer and then, loose on the drum. So after I run a board through 4 or 5 times, I turn off the machine and re-tighten the sandpaper. Often times I’ll get a 1/4-inch of slack out of the paper. Try that.

I have the 22/44, and as Tom says, best to wrap the paper tightly, run it for a couple of minutes with no load, then retighten if you can.

Mine will pull loose if I don’t have enough paper into the little spring clamp and I take a heavy cut.

Also, you can space the paper out a bit on the drum, make sure it is not overlapping at some point.

All the best!

Hi Ellen,

Have you tried calling the company? It might be something with your machine that they can help you with.

Good luck, sounds frustrating.

Thanks everyone.
I’m going to try tightening the paper after I clean off the roller. Then I’ll run it without wood for a few minutes and tighten again. One of the problems is that they put the spring clip in about the worst possible position and it takes a while to get everything situated. I’m thinking I need a very small curved needlenose plier to get in behind and pull. Necessity is the mother of invention… I’ll look around and see what I can find or make.
I really think it might just be loose paper.
Thanks again, everyone. LJs are the BEST!!
Ellen

Jet have a small hook available for pulling on the spring clip… you could probably make one…

I have the Grizzly 24” drum sander, and I ended up using duct tape on each end to keep it from tearing, it is awkward at best to get the paper tight, you need at least three hands.
