In fact I did so by mistake. The motor on my Rivett lathe is a Demag. They make cranes. I asked the vendor if it was a conical-rotor machine, and they assured me it wasn't. But they were wrong. It's quite clever. The fan-housing is stronger than normal, and holds a friction surface, and there is a matching friction surface on the fan rotor. The rotor and stator are slightly conical, so as well as the torque that any motor makes there is an axial component of the force that pulls the brake off of the friction surface. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
