[SIZE=3]Hi All,
It's been a few years now since I've owned a C-36 but I still think of you guys. I hope all is well with the current crop of C-36ers!
For years I have been trying to describe, as have others, in words, how to "pot" or fill deck hardware penetrations with thickened epoxy to seal the decks core from further moisture damage.
I have also been trying to describe why a slight bevel or chamfer to each hole that penetrates the deck is a good idea. Sometimes folks understand it via words, and sometimes they don't.
I have had this article on my mind for years and finally over the last month or so had the chance to make it all happen with some late nights in the barn.
As far as I know this is the only article of it's type that uses deck lamination cut-a-way samples to show what goes on inside the deck when you "pot" with epoxy and countersink the bolt holes..
I hope this helps make some sense of something that really isn't all that difficult to tackle just difficult to describe..
If you see any typos, and I'm sure you will, please let me know and I'll fix them as soon as I can. I'm not a writer, but do have a lot of tricks & techniques I've learned over my years of boating that I like to share with fellow boaters. Some of these I feel can best be illustrated through pictures, with the help of some words of course..

I had leaks around my ss hand rails, removed then and used a "key hole" router bit in a Roto Zip to cut out the core between deck and linner, filled this with thickened Mas Epoxy, put fender washers under posts on hand rail and bedded with 3M 4200. works great! I plan to due major refit in 2010 when I pull Spanki before moving her to the coast from Grand Lake in Eastern Oklahoma. Should I go to East Coast or West, anyone know the cost difference?:)

Spanki, it all depends on what part of the coast you are looking to go to (north, mid or south), there can be big price differences between them. Offhand I would think the East Coast might be a little more affordable than the West. I would suggest you do some research to first determine what areas are of interest, then you can compare them.

A problem I had with this procedure is that the Dremel bits are either too long or too short for the thickness of my deck. I used some shorter bits, one of which he mentions elsewhere. That worked ok, but I could not tell exactly when I was cutting wood and when I was cutting fiberglass. In his pictures, he shows it cutting out only the wood core. But as one moves the bit up and down (which one has to, since it's not exactly the same length as the core material), how does one know where to stop so that it does not cut into the upper or lower fiberglass?
The problem I have with this procedure as shown is that if one leaves any core wood (due to the problem above), then one has only a VERY thin layer of epoxy at that section of the epoxy plug, once one drills the hole. If that ever cracks, one is right back to square one with a deck leak into the core.
In summary, to use this procedure as shown, one has to know EXACTLY where to stop cutting vertically. How does one do that?
(I posted this question to him as well. Will let you know if he answers.)
