G’day I use one of those much reviled rolling mills with the long
crank handle and no gearing with no trouble. I am 5’2" and nearly 79.
I recently had two little schoolgirls here aged 10 and 12, and they
rolled one of my home made sterling 5 mm rod ingots down to 2.5mm
strip from which to make themselves a ring each. They had no
difficulty, and thoroughly enjoyed themselves. (and a couple of their
friends wanted one too!) So much for great big tough El Macho
Americans jewellers!!! Takes all sorts!
