We used to make things in this country, Rawhide or metal?


Were there actually rawhide gears? 
Robert Gardner set his company up in 1850 as Robert Gardner, Novelty Iron Works to make machinery for candy and biscuit making. In 1934 the company was sold to John Braidwood.  Braidwood Industries is still in business as a gear maker.

Maybe rawhide gears were predecessors to fiber gears and sprockets, like you find in a '60s Volvo cam drive. Sacrificial parts, meant to strip before something expensive can break in case of a seizure or similar calamity.

Yet another fascinating rabbit-hole, thanks Mr G !
As best as I can understand, rawhide gears were cut from stacked layers of bronze or steel and some rawhide-based material. Wow !
