Dan,
There is power to the unit at all times, as indicated by the "0" on the rpm indicator. I've gotten used to it, and don't see any reason to put in a switched outlet. I guess it wouldn't hurt if you were doing some rewiring, but with all of the constantly on electronics around my house- PC's, wireless modem, printers, etc., it hasn't occurred to me to do so.
As far as getting it down the stairs to your shop - shouldn't be a problem. When I picked my lathe up at woodcraft we broke down the pallet and removed the boxes containing the legs. The rail assembly, with headstock and tailstock stayed on the pallet, which 3 of us lifted into the bed of my pickup. the legs, in their separate boxes slid in next to the pallet. When I got home I unloaded the legs, took the headstock and tailstock off the ways, then unbolted it and moved it into my shop. My shop is right off the garage, so I didn't have to move anything very far, but I managed each of the pieces by myself. A helper would be great to move things downstairs. As far as assembly goes, I laid the main section upside down on some cardboard, attached the legs, then rolled it over before putting the headstock and tailstock back in place. Managed to do that by myself also, but again, a helper would be great!
Hope this info is of some use, and yell if there's anything else I can tell you.
Ron
