I’ve had a tremendous stroke of luck. A few weeks ago I able to buy
several drawplates for a very favorable price. Believe it or not,
they are all Joubert and Perelet! I did not think the seller knew
what he had and I was not about to tell him. They had few rust marks
on them and the holes are clogged with what looks like really old,
dirty beeswax. What is the best way to clean and prepare them for
use? Some of the plates are for pulling wire as small as 30 gauge,
is it better to use beeswax or drawplate lubricant for those plates?
