Re: OT: Automatic bike transmission

My dad had something like that on his Minneapolis Moline combine. The moveable parts of the pulleys were connected by an arm that would move them to keep belt tension consistent. I don't remember how the operator made the variable speed part change speed. The unit might've been made back in the late 1940s. There wasn't anything complicated about it. There was a 3 speed manual transmission ahead of this. The variable speed gizmo let the operator fine tune speed. MM called the unit a Uni Harvester or something like that.

Yeah, I fractured my right large metatarsal that way when I was about

10, somehow fell off my BMX at slow speed.

Had no idea at the time how it broke exactly nothing felt wrong until I tried to stand and I couldn't, I remember it being a extremely painful fracture compared to e.g. a broken toe which wasn't that bad. I don't know if treatments have changed for that much in 30-something years, at the time it meant a full cast up to the knee for about 10 weeks.

Glad I was with a friend at the time because it was the middle of the day in a dirt lot in a somewhat deserted suburban neighborhood still under construction, before cell phones obviously, there was no way I would've been able to walk for help myself.
