Hey Don: I have a Delta 31-695 belt/disc sander. I 've had it about 10-11 years. It has a 1 hp. motor, is 10 amps, 1 phs., and turns 3450 rpms., and comes with a Delta stool stand. I've used this thing a lot, and only recently changed belts and disc on it for the first time. The dust collection on it is not the best, and was set up to take a shop vac hose. Under the belt is a "slide plate" where you can shut off the dics, and get belt dust only, or open it and get the disc dust(?), and shut off the belt. It's pretty noisy, and has kinda of a loud"kick" when you turn it on. It has a belt tensioning handle that you flip to tighten and loosen the belt, and a knob up front to "track" the belt. It's been a good sander, and still is. I've re-worked the dust collection on it, tried this and that , fixed a couple of jigs for dust collection-all no good. So-I'm back with the original d.c. It helps a little when you swap the plate from disc to belt, but not much. I bought a mobile base to move it around the shop if needed. I think I gave about $169 at the time. Too bad they stopped producing them. They were pretty good machines for the buck. I didn't know they had. I never really cared for the open stand, but hey, it serves the purpose. Hope this helps. If I left anything out you needed to know, re-post. Rick.
