10-4 thank you. Yes I got everything removed all the way down to and including the nut that holds the wheel on....and yanked. And yanked. And yanked...no joy. Figured I was missing some sort of ring clip or something. Put it back together for the moment. Fishing trip tmrw got cancelled, so looks like I'll be sewing instead.
A side-to-side violent rocking usually pops off the stuck ones for me. But keep the nut lightly threaded on to avoid a trip to the dentist.
