Well, I'm not with Stupid................ I am Stupid.
After trying the recommended heat & bash method with no luck, I decided to completely remove the little bolt that tightens the wheel to the shaft, instead of just loosening it..............
......... and the wheel then fell off in my hand.:o
It turns out that the bolt serves two functions, it not only nips up the tightening groove in the wheel (the obvious function), but.......runs through a groove in the shaft itself, and serves as a lock to prevent the wheel sliding up or down.
Now I've got a flat spot that runs half way up the shaft, where the bolt dragged its way up. :o:D:D
Is it too early for a drink?:(
