Default bolts rusted in to cast iron bench

Cast iron is very strong but brittle - whacking it is never a good
idea.

The bolts are 10 mm and project about 6 cm through the metal.

Any ideas how to get them out?


If you haven't already done so cut the wood off close to the ends so
you can get at things a bit more easily.

Soak the nuts regularly in WD40 for several days. Contrary to
popular prejudice WD40 is one of the best penetrating fluids around.
If that doesn't allow you to remove the bolts then apply heat from a
blowlamp to the end in the wood. Either you will be able to remove
the nut when the metal gets hot or the wood will burn off allowing
you to cut the bolt with a hacksaw.
