Title: Drum Sander Gummin up.
Post by: Mark Smeltzer on November 05, 2015, 08:46:00 PM

Is there any way to keep the drum sander from gummin up with oily woods like cocobolo and bocote?
Thanks,

Mark

Use coarser paper. I use 60 grit. Finer passes and a good dust extractor.
I used to have problems with 80 grit but not anymore with the 60 grit.

most wood working stores will have a 1 1/4 inch square X about 8 inches long piece of rubber that looks like  art gum eraser.  They are made to erase (clean) the build up on sanding belts and they work very well.  I have one I have been using for over 2 years and I would not be with out it. I use it on my belt sanders and drum sanders with equal success.  Seems like they are only $4.00-$5.00

I have one too
With bocote you need to use it very often
and I still had to pick/scratch it out with the point of my compas.

I'll have to get one thanks for the tip!

Its fine passes that will allow your dust extractor to 'pick it up'instead of it clogging your paper. Very fine passes. Once the paper gets hot from cutting too much wood in one go the dust will stick to it much more readily. I use my 'eraser' all the time as well.

I found that sometimes a soft wood like poplar or alder will degum the grit.   A softer wire brush works.

The eraser helps but a very light pass helps more.  Cedar and Osage can be gummy also.

I use 60 grit mostly now in my wide belt and don't ever have much trouble with gumming. The oil is seldom the problem either. More than likely the wood is a bit wetter than it needs to be. That will cause it to stick to your belt...or taking too much with one pass.

A quarter turn on my drum sander adjustment is 0.4mm, which is about 1/64", I think. I rarely grind more than one quarter turn at a time - it takes a few passes to get lams done, but you get a terrific result.

yep you guys are right as usual. I have been taking too much off per pass especially on the oily woods.
Thanks for the help.
