Disposals
I bought an ISE model 77 back in '93. 3/4 hp, reversible, it handles corncobs, bones, whatever. In 2000 the hammers began rubbing against the grind ring-the slots in the hammers had worn. I pulled it apart, replaced the turntable and grind ring, lubricated the motor bearings, and reassembled it. It's still running great. I'm not sure if the new ISE's are rebuildable-I've heard that the grind ring is no longer replaceable, you have to replace the housing. The turntable is, however. When the time comes, I'll probably buy another top-of-the-line ISE. The induction motor, by the way, is far superior to the permanent-magnet brush-type motor used by the "high speed" models. Those have a limited life span, determined by the life of the motor brushes. Generally new brushes aren't sold (though you can go to an electric motor shop and find something that will probably work), and when the brushes wear out, the commutator is probably shot, too.
