Today makes the second time I’ve broken the sandpaper on the drum sander in the past week and third time in the last month.

I was sanding a 24”x24” piece of bubinga and maple for my 12th year wood shop project when the paper on the real drum was torm at the left side clip that held it to the drum. All three times the sandpaper roll broke like this, on the rear drum at the left side clip. The machine we have is a Ledacraft DS-25.

One of my classmates just replaced the sandpaper on monday after I broke it last week, and he had do it again today since I’ve already developed the reputation as the kid that screws up all the time and can’t be trusted to do that kind of work. Somehow all of my classmates are able to use the drum sander without any problems, and leaving a small pile of sawdust on the floor beneath the exit side of the conveyor belt, whereas I was only taking off a small amount each pass and my pile of sawdust is nowhere as big as theirs.

Anybody know what I might be doing wrong?

The main reason for tearing of sandpaper on sanders is pressure. Try taking lighter passes. I normally will lower the head down on to the board while the head is running. This allows we to hear when the sander is making contact. Then I will back it off a 1/2 turn for the first pass. Then go a 1/2 turn each pass
