OK, got it done!
Man, that freewheel didn't want to come off at all. Talk about tight! I thought I was gonna crack my sawed-in-half sternum. It finally broke loose though.
Wheel bearings were bone dry so I lubed them. Made a jury rigged system for truing the wheel. It's not perfect but I didn't want to break any more spokes so didn't give it the full monty on adjusting it true. It might have .015" runout total.
Felt good to help out an old friend. When he suggested using super glue on the broken spoke I just knew I had to do something.
Plus, I've got a new tool now too. The Shimano wrench should work on my own bikes too.
