Topic tags/keywords: orbital sander gouging

I have a dewalt variable speed orbital sander, one of the older ones with a round top instead of the oval ones they have now.

It was working fine, ive been using it for about a month on the same stock of douglas fir, but all of a sudden it seems to be gouging even with new paper. I can get through them using a lighter grade paper, but it wasnt an issue before.

I slowed the sander down and it helps, but it still does it.

Im not pushing down or anything, but is there something else im doing wrong?

sounds like your disc has a tear in it.

Is it actually orbiting or just spinning in a circle like a grinder ?
If you’re getting the grinder action , that means the “brake” is broken on your unit.
Easy to fix…look at the parts / repair manual and replace the broken part. Parts diagrams available online.
On my PorterCable units , it is just an O-ring type of device.

My DeWalt did that when the brake wore out. Took it to the service center and they handed me the parts. Easy fix.

I’m with Jim. Check the disc for a tear or perhaps a small glob of glue? You can buy replacement disc at Lowes or HD pretty cheap. And the disc should come with a new dust skirt, replace that too.

Im trying to remove deep milling marks and bought a belt sander after realizing that the oscillating sander wasnt removing enough and i dont have a planer. Im using the belt sander to remove milling marks, then oscillating to remove the sanding lines from the belt sander.

What i realized was happening was the belt sander was gouging the stock but i didnt see them till the oscillating pulled the packed sawdust from the gouges. I vaccumed off a few pieces i hadnt hit with the oscilating sander yet and there they were.

Live and learn! I need the replace the dewalts switch, ill do the brake & disc as preventative maintenence.

mtx77- A drum sander or a planer would be a big help to you. If they’re not in the budget, start trolling Craig’s List for a bargain. Those are 2 of my favorite tools!
