Tolivac, the rear tailgate on the Rotopress opens at the top in the conventional manner, thereby getting the feed cone/screw out of the way, so the load just comes out through an unobstructed opening. These will probably eventually become popular in the USA for collecting recyclable paper and for collecting compostable yard wastes in suburbs. One wouldn't use them for grinding up refrigerators, since that would enable CFCs to leak into the atmosphere.
Next time I have a design project for recycling hardware I'll go look up your CRT site there. I have one more invention for that industry from my 1983 design project, which is a partitioned container system that no one else has gotten before or since. Hmm...
Back to GE here: GE dryer, GTR-11-AAP, with a persistent intermittent squeak. It may be that the felt bearing is breaking down. In which case, how difficult is that to replace? And what's the best way for getting the whole thing apart to do it, after getting the top off? Does the drum have to be removed, and does the heater have to come out in order to do that? Or should it be taken in to an appliance service center to have a pro do it?
