When I needed a part for my Performax just recently, I talked to Jet and they told me they took over the performax small end drum sander line and that is why they look exactly like the same sander. In fact most parts are interchangeable. Could not be without it. Years ago I built a cabinet for the sander and has worked out well all these years. Keep all my sanding stuff in there and is on wheels so I roll it out any time I need. It uses a 2" dust port so my shop vac works great there even though I did and still do have a hose from my full size dust collector. But found shop vac works well.
