[C38] corrosion and Rigid Vang installation

In the gooseneck fitting there is a shaft that allows the boom to rotate
when the boom is sheeted out. I removed the fitting, oriented it so that
the boom would be in the upright position. Then I drilled a hole through
the casting and the stainless (I believe) shaft and put a bolt through them.
If you have any other questions, just give me a call 206 947-6095.

Points well taken, so what does pinning the gooseneck/boom involve?

I tried to mount my vang plate on the mast as low as practical to make the
loads more vertical on the plate than horizontal. I think this puts more
shear loads on the screws than tension loads. I would definitely use screws
sized according to the holes in the vang plate rather than rivets. The only
problem I had tapping the holes was that I didnt get one of the holes
perpendicular to the plate. A very important thing to remember is to pin
the gooseneck to prevent the boom from rotating axially (twisting). This
movement will destroy the vang.

Thanks for the comments. I'll talk to my rigger about rivets vs. bolts
...yes, I'm having someone install it...I'll put holes in the deck all day
long, but I chicken out when it comes to the spars. ;-) Good to know about
the instructions, I was about to call mark. And Jay, pictures are always
welcome!

Hi Steve,
I installed our new Garhauer vang 2 weekends ago. I drilled and tapped ¼ x
20 threads for ¼ x 20 SS bolts. We used Teff Gel as Max described below.
Well see how it holds up. I recommend starting with a much smaller hole
than you think and see if tap works at all. Our first hole has shallow
threads. Lesson learned.
We followed the Garhauer instructions. They are on their website. Once the
boom settled after initial installation it appears a bit droopy, but for
trimming the main it is necessary to go below horizontal with the boom. If
youd like I can take pics this weekend while we are down at the boat.

Steve, To avoid corrosion, you can use Teff Gel and that's it, no need for
plastic liner....That will avoid corrosion between stainless and
aluminum......

Steve:
We have a Garhauer rigid vang. Vigorous jibing by my kids ripped the
rivet-attached vang from the boom a couple of years ago. The rivet holes had
built up lots of corrosion in the 9 or so years since its installation. The
rivet heads pulled out through the corroded donuts around the holes. There
was not much corrosion between the vang bracket and the boom. We reattached
the bracket to the boom with 3/8" bolts, for which we tapped holes into the
boom. The kids haven't been able to wreck the reinstall, yet.

Hi Folks;
So I just received my Garhauer rigid vang...all shiny and new...can't decide
if I want to put it on the boat or over the mantel! :) OK, it will go on
the boat...but with that comes the question "does anyone have any lessons
learned that I should know about?" Max had indicated that I should/could put
a plastic gasket (cut from a milk jug, etc) between the vang brackets and
the mast/boom...what about the compression of the vang when the boom is
"level" (mid-range of the vang?) and/or mounting height on the mast?
Anything else to plan for?
