Topic tags/keywords: drum sander

I have a newer General brand dual drum sander. I am getting burn on the sanding drums, it seems random though. I know that I am not taking away too much material at one time because I only turn it about 1/8 of a turn per pass and I have done 50 boards this way with success. I also know that I am not hitting knots or anything, I inspected the most recent board victim and that does not seem to be the case. Maybe sap or saw dust built up quickly before the DC could take it away?? Not sure what is going on but this is a reoccurring problem that is slowing me down a lot and also using up my paper rolls which are expensive! It is never the same spot on the roller or the board so I’m not sure what is going on.

I was wondering if it was just getting hot but the pic below is the first pass of a maple board with new sand paper. It is cloth backed paper, not sure what else to tell you to help diagnose the problem? Sorry the pic is sideways

Glazing. You need a crepe rubber block.

Glazing can be got off by soaking the belt in soapy hot
water and scrubbing with a nylon bristle brush.

Heat probably contributes. Try taking lighter passes and
perhaps upgrading your dust collection to cool the drums.

Having a 37in dual drum SuperMax I have had this problem and so has everyone else. Grit,speed,debth of cut.

A little trial and error take notes. Keep your paper cleaned, do not take to much off at one time as you get into the finer grits.

In your experience does it keep the board cooler if I speed up the conveyor belt to keep heat from building or does that heat the sandpaper more quickly?

I’m not concerned with a hot board, but a hot drum, which
will stretch the sandpaper as it expands. This leads to overlapping
and that leads to trouble.

I don’t like drum sanders. They are a lot of fuss. Get a digital height
gauge and learn to take passes under 1/100” and take 2 passes at
each depth setting. This is very tedious. Once you’ve figured out how to
make it work with these very fine passes, experiment and perhaps
keep records of wood types and widths, grits and pass depths.

I had this problem for years. Loren is right you are getting overlaps an they will cause the burns. Part of the problem is the lousy clamps wt the ends. I solved all my problems and now love my drum sander again after retrofitting a hook and loop system from Grizzly. My machine is a 26” dual drum under the brand name “Canwood”. Except for the color and a small difference in the base it sits on it is identical to the. General International.
