I re-acquired a butcher block cart my father and I built years ago. A

out with wheels and I'm unable to separate them from wheel shaft.
Thread nuts are brass. I'm short on tools and hate to waste perfectly
good metal wheels because nuts are stuck. Any ideas on how to separate
shaft from thread nut without damage to either? Thanks


"Thread nuts are brass. ..."

Bad idea (as you've discovered).

"Steel and aluminum are relatively compatible, but if brass and steel
contact, the steel will corrode because it is more anodic than the
brass. .."

Brass on steel should not bind, unless the steel is very badly rusted
(and needed to be replaced).

The classic trick is to heat the nut up to about 400 F and try to
unscrew it while hot. This temperature won't hurt brass or steel, but
will char wood.
