Hi Doug:
Thanks for this--if you have an opportunity to take and post some basic photos in the future that would be great.
Best,

 The reefing line is designed to run as diagrammed on page 12 of the PDF document located here:

I redid mine a few years ago, using Jeff Hare's idea of adding ball-bearing blocks on the reef points. The car that runs inside the boom was missing so I made a new one using a couple of ball-bearing blocks shackled together.

This new setup is smooth as silk and requires almost no effort to reef down.

Here's the article I wrote up a few years ago describing what I did. Unfortunately, the photos have been lost.
