[Rhodes22-list] Converting Electric Winch Motor Lift to a Manual System

[Mike Riter]

My '89 Rhodes came with the manual lift and goes through 6 blocks (3 top, 3
bottom) The amount of pull is about the same as everyone else has stated.
My co-capitan can't raise the motor without threatening mutiny. I'm working
on a different mouse trap using a threaded rod and a winch handle I hope
will make the raising/lowering a much better experience. That project will
take some time to work out all the details.

Meanwhile, I've added another block to the stern rail directly above where
the line for the lift comes out and extended the line so it will reach the
port winch. Being able to winch it up works pretty well. As with all the
manual hoists, gravity pulls it back down.

Rick Stott and I have been working together on the screw style design. He
would like to see it be electric, I think I'll be happy if we can make it
work manually. My hope is the threaded rod will stabilize most of the load
and the aluminum channels on either side will work as guides to keep
everything aligned. It should also be stable at any height or depth. Kind
of a set it and forget it thing.
