:D I'm good for weird ideas that work. Like.... using a "scrap booker, die cutting machine" and steel ruler dies... to cut leather. But sadly my guy that made the dies quit.... <sigh>
I once considered one of those old ringer washer machines... but finding one with intact ringers... and not all cracked and falling apart would be kind of tough and probably expensive.
Be careful of metals.... remember leather typically has tannens... which react and turn black when it touches metal (steel, iron... think Vinegaroon) So.. maybe replacing the rollers with some sort of plastic ones would be better.
