.... It acts like a stuck sheave but remember in my original post I stated
that I checked the sheaves and they spin free.

They may spin free when unloaded, but not under load. How long have the
sheaves been out in the weather?

Around here you can tell which neighbor has ungreased sheaves by the
squealing noise when they operate their lift.

That's something I hadn't thought of, and the answer is about 7 years. Lift
was very rusty and the sides of the cradle beams were flaking out (rust and
corrosion) and pinching the sides of the sheaves.

The only other thing that makes any sense is the cable that snarls is
a little longer than the others. I have 5/16" cables with nothing but
a hook and a 5# weight that stay tight. when I run them up.

With the cradle off the bottom but down does there seem to be a
littler more "wiggle" in a diagonal pair? If one pair are banjo
strings and the other two have some wiggle you have your problem.
Shorten one up a bit.

Maaaaaaaan..... that might just be it. I will check it tomorrow though.
Even though the problem cradle appears level from inboard to outboard side
it makes sense that the cables are not the same length. I would think that
it would take up its own slack and just hang low on the canal side but I
will compare tension tomorrow. If that's it, I guess I just unspool them
all the way and slide the cable through the spool holes just a bit to even
em up right?

If not, you can probably solve the problem by adding some extra weight
on each side of the bunk boards. An inexpensive way to do that would
be PVC pipe filled with concrete and/or rebar.


The End: Problem WAS related to "buoyancy" from the two large 2x12 bunk
boards. I added a piece of 2 foot long rail from a nearby train yard.
