Keelson repair
Posted: Fri Aug 17, 2007 6:24 pm
On a 1960s Sea Coaster, I have the garboard planks off and am starting to repair the ribs, which have rotted at the keel ends.
I have found some rot on part of the keelson. The center board in the keelson is sound. The bottom edges of the outer keelson boards (that sandwich the center keelson board and to which the ribs are fastened) are black and rotten for about 1/8 to 1/4 inch deep for much of their length. The rest of the wood on those boards is solid. The question is how to repair these boards.
My thought is to scrape/chisel the rot off the keelson and apply CPES to it. But I'm worried that the bottom surface of the outer keelson boards will now be higher than before, and that the ribs will therefore be too high to be flush with the garboard planks. Should I shim the ribs down with oak, or build up an epoxy buffer, or try some other method?
Thanks for all input.
