I've done about as much as I can do before getting into the metal shop for welding. I even got a scrap hub from a neighbor's junky bike so I can make a jig for bending the rear triangle down.
I think while I'm waiting to weld, I'll take one of the Nishiki's wheels and use it to learn how to build a wheel. Take it completely apart and re-assemble, just for fun. I can also get rid of all the rust and shine it up while I'm at it.
