I bought a performax 25/50 drum sander (scratch and dent...a big dent) at a good discount, called laguna tools and they sent me the end of the dented cabinet for shipping cost. Anyway; after several months of using it, I would have rather put the money in something else. Gums up too easily, burns too easily, leaves sanding marks that take forever to sand out. I think part of the problem is no cushioning behind the sandpaper? It would be very useful for a luthier or someone that does veneer repair, or used figured wood a lot. It seems to go out of adjustment pretty easily too, and takes awhile to set it back to being square with the feed table. I've tried zircon paper, thinking it would clog less; nope, probably clogs more. If a sandpaper maker would make a synthetic rubber/cork backer for the sandpaper, I think that would help quite a bit? I bought it thinking with 80 grit; I could flatten slightly cupped live edge boards. Nope, not enough power, and it would take till eternity to get it done. What do you guys think?
