Boom Ring String
- Hi All
I read about string re-enforcement of our boom rings. This sounded
great since I have split 3-4 rings over the years (One at the most
recent mid winters). The how to do this was less than instructive.
This is how I did it I have included photos in the photos section.
I have a small drill press as well as a Dremil tool. The Dremil tool
rpm was to high to control the cutting. However, the cutting disc was
the perfect tool.
I made a small wood block with a close-pin CAed to one side. This
made a stable and easily leveled working plane. I held the close-pin
in a small vise and could level the block without difficulty.
I then rough adjusted the height of the block to the Dremil cutting
disc, that was in the drill press chuck.
Putting the boom ring flat on the wood block I fine adjusted the
height of the cutting disc in the chuck and tightened the disc in
You want a relatively slow rpm 300-500 rpm. This is fast enough to
cut the plastic with control of the boom ring under your finger.
Cut a shallow channel around the boom ring.
I use 80lb spectra fishing line from "Power Pro" ( I also used this
for my standing rigging). Cut a piece of line approximately 10-12
inches long. Tie a small knot at each end this is to prevent slipping
when you tighten the spectra around the boom ring.
I used a small vise grip to hold one end of the line with the small
knot in the jaws.
Then tie a large over hand knot in the line and place the boom ring
inside the knot. You need to anchor the vise grip I used a second
small wood vise on my bench. A clamp or other method is fine as long
as you can't pull it free.
I used pliers on the other end of the string (my son lost my other
vise grips) and tightened the knot around the boom ring. At this
point you can adjust the boom ring in the knot so the knot is at the
top of the boom ring. Increase the tension of the knot and add a
small drop of thin CA glue. If you have CA accelerator a small drop
or one misting will set the CA.
Clean the accelerator with a paper towel and using a razor blade
(exacto blade) cut the excess string off the boom ring.
Good Luck and fair winds.
