I have a Supermax 19-38 drum sander and am considering an upgrade. I wasn’t sure how much I’d use it but it’s become a key part of my workflow. A project now starts with wood that is perfectly dimensioned with no mill marks and no snipe. My shop is pretty full and I have no space for a wide-belt sander plus I really don’t want to add in the additional infrastructure (i.e., compressor) that a wide belt needs. Are there any drum sanders out there that are a step up in quality and power? The open-ended design has always concerned me and I spent a bunch of time making sure the surfaces were parallel; I’d rather go with a closed design that is more stable. General seems to be out of business. Grizzly now has a South Bend drum sander but it has zero reviews. Anything else that would be considered better than the Supermax?
