I like your providing him with the analysis of what the individual and
combined forces/tensions would be Dave.
The WG2000 from the same source is $77.80 and is a worm gear winch
with 40:1
turns ratio. None of us is getting younger and having something that
cuts
the cranking force by a factor of 5 or so might be of interest. In
addition,
the worm gearing provide breaking that you don't have to think about.
--------------------------------------------------
That WG2000 is a nice looking winch for $78. It holds 82' of 7/32
cable.
If you had about 100' of cable, you could cut the raising forces even
more by doing the following:
1. Mount the pulley 5' up on the tree.
2. Loop the cable through a pulley 20' up the tree.
3. Loop the cable through another pulley attached 20' up the tower.
4. Attach the cable firmly to the tree, just above the tree pulley.
