Several of our pan lids are now decidedly unstable and fall apart at
the slightest opportunity - potentiall dangerous when hot. And very
annoying. The pans themselves are of "lifetime" quality, metal with
copper bottoms - I don't want to replace them.

The majority of these problematic pan lids have wooden knobs,
attached via a metal bolt. The thread on the inside of the pan lid
has essentially worn down over the years, and now doesn't allow the
bolt an adequate "foothold".

Mix up some of this or similar, & put it in the thread in the knob. Screw
up & leave for an hour of so.
