I bought a hand cranked clothes wringer off ebay. Gotta have a way to squeeze water out of the clothes and not get a blister on my hands. It works like a charm.
I do think that you are worse than me.
Why didn’t you get the gasoline motor on a Maytag wringer washer? Then it would do most of the work for you.
At least it is not a rub board, they ruin your hands.
