A nut buster is sometimes the best and easiest solution, if you can get
it on the nut, and if the nut is a "low value" one. It is frequently my
FIRST choice.


I'm afraid you misunderstand the issue. Removing the nut is not a problem. I
removed it and put it back on the bolt to protect the threads. The problem
is removing the stainless bolt, which is, not surprisingly, corroded to the
aluminum stanchion.

ah.

Sorry for missing that in this (long) thread.

Indeed, stainless and aluminum are an evil combination. I have a mizzen
mast with a seized aluminum sheave (it runs, or more correctly "ran" on
a stainless axle) - I can commiserate.

Dave,

Glacial Acetic Acid is almost pure acetic acid. Any chemical supply house
will have it in small bottles. Be careful while handling it. Add acid to
water rather than water to acid when diluting. Et c.
