I was trying to inspect the backing plates for the bow pulpit on my O'day 35 the other day, but was also having a bit of trouble finding them. It seemed that at some point in the past that the pulpit was re-bedded with what I believe is 4200. After I found the nylock nuts holding the bolts in place, I realized the problem; there there weren't any backing plates!
Poking around in the forecastle (or, what ever you call this space)
some more, I found what I believe was an old fiberglass backing plate resting, unused, inside the cabin liner.
Don't start on me about the mickey-mouse crimps on the nav. lights - they're on my "to do" list.
This "backing plate" is 3-18" in diameter, 3/16" thick, is gelcoated on one side, and has three bolt holes in it. The gelcoat color is a match for the cabin liner, and it is clearly made with very heavy cloth. I suspect that this plate was original to the vessel, and cut from a piece of scrap cabin liner material at the factory. It seems that during the re-bed operation, the holes drilled in this piece for the mounting bolts didn't line up, so persons unknown put it down and forgot about it - and the three other required backing plates. I also found an unused stainless washer, just the right size for the bolts, sitting in there too.
A friend of mine gave me a couple of scrap pieces of Ľ" G10. Each of these scraps are big enough to cut two new plates from. My thought is that I would;
- drill one bolt hole in the backer plate
- remove the pulpit mounting bolts
- wipe the area where the plate will be mounted with acetone
- use 5200 to stick the new plate in place
- hold the plate there by replacing the one bolt and washer through the one hole.
Once the 5200 sets, I would then remove the one bolt, pot, and redrill all the holes through the deck properly, ala MaineSail.
"Why 5200 to stick the plates" you ask? Because it comes in a small easy to use tube, and because it has some flexibility to it once it cures. It also has a tenacious grip, and I don't want these plates removed. Epoxy would be great, but I would have to grind where the plates will be mounted, mix, add fibers, mix some more, and then get it to where I need it without spilling, or making a mess, before it begins to kick.
"Why G10?" My thinking is that these are 1/16" thicker, and therefore stronger than the originals, there are no dis-similar metals issues, and the price is right
. I considered 6061 Aluminum, but it would be close to $100 (including shipping) to buy enough of it, and then I would have to worry about galvanic corrosion.
That's my theory anyway... Is anyone willing to poke some holes in it?
Thanks in advance!
