fastening  05-08-2003, 03:07 PM I realize I've been awfully
noisy, but with my project coming up I need lots of advice!!!

boat with hot dipped galvanized screws of decent quality. I got
to thinking about the factors that cause them to waste away, and
I realized one of the main ones was the plank/frame interface.
What if you core drilled out the old fastener, made up a dowel
with a blood groove, epoxied it in place but left it proud by
the same thickness of the plank that you have left as meat to

interface instead of metal.  So, for example, if your fastener
was 1/2", the dowel would be 3/4", so that gives us 1/8" of good
wood all around the new fastener. If the planking was 2", the
dowel would stand pr
