Well, I had some slight success with light passes and waiting if the wood got even the slightest bit warm until it cooled down. This with 120 grit.

Also tried wiping it down with denatured alcohol. Didn’t see any difference there at all.

By the time I had made 6 or 7 passes thru the sander, though , cleaning the belt with a crepe stick every second pass, it still bogged down and burned the wood. (only the purpleheart, the maple seemed to work fine)

Fortunately, by the time I had done all this, the board was as flat as it was gonna get. All that was left was some work with a ROS and a card scraper. It is as smooth as a glass plate now. That endgrain hardwood is some tuff stuff. Tomorrow i’ll round over the edges, and apply the finish. I think I’m done using purpleheart for endgrain boards though. Still have two more to make to take care of all the kids, but we’ll switch to maple and walnut I think. :-)

Bottom line on my new drum sander is I love it. Just have to watch what goes through it. Does amazingly on face grain boards. Looking forward to using it for a long time to come.

Thanks to everyone for the suggestions. I’ll post a pic when the board is finished.
