Does anybody know if there is a formula for working out the cut-off angles for fitting abrasive paper to a drum sander. My problem is that I have not been able to get the paper at the same width as the one fitted to the machine when I purchased it, so cannot rely on using the same diagonal end cuts. I get the first end in but after winding I find that I am either too short or too long for the slot at the other end.

Any advice would be most welcome…

What size drum sander, I have a 13in and a 37 inch. Knowing what size someone could measure the length. So if yours is either a 13 or 25 or 37 I can measure for you if that helps. On the back of the replacement paper there are colored lines that I have to cut for what size I am needing. Brand name of your sander would be helpfull as well.

Just guessing, because I have not actually tried it, but the length of the diagonal cut should be the same as the circumference of the drum minus about 1/8” to provide a small gap. Wind the paper around the drum until it hits the other end. Some widths will line up with the clip and other will not. It seems like you have to find the proper width of paper for it to work properly.

The popular drum sanders, like Jet/Performax, will have multiple suppliers competing to supply sandpaper in the proper width. What brand and size is your sander?

When I made my home made sander, I made a long strip of paper. Wound it around the drum, marked the ends, removed and used it as the first pattern.

Thanks for your responses. The dimensions of my Drum Sander are as follows:
Drum length 410mm – 16”
Circumference 426mm – 16 3/4”
paper width 82mm – 3 1/4”

I will try cutting the diagonal the same size as the circumference and see what happens. What is strange is that I tried cutting the diagonals the same as the paper that was in the sander when I got it. The paper I am using now is perhaps 1/8” narrower than the original but when I tried to fit it the end was nowhere near the clip.

Footnote….

The Drum Sander is not one of the common popular brands. It comes from Poland but is designed along the lines of the Jet models.

If your paper is 1/8” narrower than the original, then it would seem like the easiest solution is to increase the gap by 1/8” when winding. Otherwise, the end will land in the wrong place and will not line up with the clip.

A more extreme solution would be to cut another slot in the drum so you can move the clip to the location that works with the paper you have.
