View Full Version : Which Pulley?

The winch discussion has prompted another question for me. When using a
winch there are two basic options for the way it is rigged. The closed loop
method raises a question. In the closed loop (for those who don't know) the
winch runs a closed loop of line through a pulley and the sheets are then
attached to this line. My question is about the turn around pulley, who
makes the best? And why? And how big should this pulley be (compared to
the boat of course)?

I have a small sailboat called the "Tradewinds" by Kyosho. My closed loop
pulleys are just screw eyes with the loop running through them. Not the
best setup, but it works. If you want a good source for pulleys check out

What I have used is a patio door wheel. These are deeply grooved and the
ones I got are ball bearing. They are about 3/4 to 1 inch in diameter. I
have the servo, rudder servo, battery and receiver on a radio board which at
one end has a platform to hold the battery, servos and receiver and at the
other end a block of wood to support the pulley. This is joined together by
two pieces of carbon fiber rod. A platform in the middle is secured to the
bolts that hold the keel. The distance between the sail servo and the
turnaround pulley must be greater than the throw needed to let the sail in
and out. A small spring in the line keeps the line from sagging. The pulley
and the sail servo are at the same height. The idea was taken from US Boat &
Ship Modeler Fall 1988.

Bill,

Thanks! I have a friend who does the screw eye thing as well. Fine for
small boats but I'm dealing with a 6 Metre which is 60 inches long. I've
been to Great Basin too and they have great stuff. I was just wondering
what others have used.

Thanks again,
F.H.

Bigger is better, and I'm on the patio-door thing as well. Excellent.
My Atlantis uses turning blocks that about an inch in diameter, but
they're simple bushed thingies. I'll be replacing them.

I just replaced my dad's open-ended loop with a closed loop in his
EC12. It works well, thank goodness. Anyway - I was proud of my
tensioner. Working late one night, and having no springs available, I
looked around and found just what the doctor ordered - music wire.
Remember that I was faced with adapting an existing setup, so I didn't
much wiggle-room. Right in the middle of the return-to-winch line,
which zoomed past my radio board, I just bent the wire this way and
that, screwed it to the radio board and hung a small block on the
wire. The return line went through it and a couple tweaks with
needle-nose pliers resulted in a nice taut line.

My Atlantis has one of the turning blocks (there are 3 - sheesh!)
mounted on a spring to keep the tension in there.

Howard,

Hadn't thought of the door wheel. Great idea! Thanks!

I'm using a PeKaBe block in a 5 foot skipjack with a huge sail. No
problems.

A simple way to keep tension in the loop is to tie an O-ring to the loop
with a bowsie to adjust the other end. Experiment with O-ring sizes to
match your conditions.

Yep! I settled on using the PeKaBe stuff. Very nice stuff! Work will
continue once I have a few Honey Dooooos out of the way.

Thanks for the response.
