I have a problem of what type of keel bolt material I should use with
an oak keelson and an Iron keel. If I use 304 stainless steel the tanic
acid in the oak attacks the keel bolt and the stainless keel bolt is
more noble than the cast iron and the stainless attacks the iron. In
the old days they used a material called Black Iron. I have not been
able to locate any black Iron. I did a survey on a 1935 schooner called
Dabloon. I had the black iron keelbolts ultrasonicly inspected and were
good. Oak Keel and iron keel. Those old guys sure could do it right.
They also coated the bolts with red lead.
Send me an email if you have the answer
