This afternoon, I went out in the woods behind my garage and dug out
the original tension limiter winch base and brushed off the leaves to
take some photographs. The base is rusty and the wiring is shot but
could be refurbished with a little sand blasting, painting,
and replace the wiring.
We ran one of those in Cincinnati, for years, It was mine that I had built,
from the plans, that I think I still have.
We quit using it for the very reasons that Chuck has stated.
I ended up giving the frame away...Damn it was 30 years ago

I did and used such a winch over 30 years ago.

Yep, that's what I was thinkin
Tony, I have given the auto line tensioner a bit of thought. Measuring with a
three pulley sort of thing and a strain gauge on the moveable pulley or an
optical sensor approach should be pretty feasable and low cost. Two problems
remain: a motor controller will be very expensive for any analo
There have been various proposals about limiting winch current via a series
resistor, but nobody has mentioned directly governing line tension. It is
certainly possible to devise a gizmo that would measure line tension, average
it over some desired interval, and limit current flow to the winch s
