I'm considering purchasing a wide drum sander like a Performax 22-44 (or a Woodmaster, Delta or Grizzly comparable machine). I am often making cabinet boxes with veneer plywood and would like to speed the sanding time for early grits like 150 or 180. I figured I would still need to finish sanding at 220 grit with a random orbit sander, but I'm unsure if the drum sander would be too aggressive and burn through the plywood easily. Most of these cases would be painted so slight burn through wouldn't be the end of the world, but complete burn through to the core layers is unacceptable.
Does anyone have any experience that can help my decision. Thanks
