Dave, If the slide rule is a wooden one, there is sometimes a spring
deliberately designed to push the A & D scales together to compensate
for natural movement in the sliding section.
Graphite from a B pencil rubbed on the sliding surfaces can be helpful.

Rubbing beeswax or a candle on the sliding surfaces can also help (and
won't leave marks on your fingers, etc.).


Beeswax is sticky so not suitable. Paraffin ('ordinary') candles would work.

I might revert to an angle grinder yet :-)
