Yes, I have to agree with Charles on this issue - lots and lots of wooden
boats here in the PNW are fastened with stainless screws. In fact, I have
just put close to 7000 in my hull during its refit and under the advisement
of one of the most well know wooden boat builders in the PNW.
I saw a rather sad occurrence earlier this week when a local chap, who is
also doing a refit on his wooden boat, started to refasten the hull below
the water line with silicon bronze screws that he had imported from on of
the well known eastern US suppliers - about every 3rd screw would just about
come up tight and then the head came off. Now we are not talking about
trying to drive the screw blind into oak or such hardwood, we are talking
about a guy who had the correct tapered drill / counter bore drill and was
driving the screws with an old style brace and driver bit. In looking at the
screws that failed we could not see anything wrong like cracks or such, they
just did not seem to have enough strength and these were # 12 X 2 1/2 screws
not little by any means..
Sure glad that did not happen to me as I used a cordless drill / driver set
up and drive the screws (same size) until the drill stalled. In all the
screws I used I only damaged about 20 and that was due to the driver
slipping.
I think that since this issue has been chewed to pieces at least once before
on this list, it comes down to a persons personal opinion possibly based
again on personal opinions of the shipwrights in the area they hail from.
I personally know of a 60 foot charter boat locally that I observed being
refastened about 10 years ago with stainless so I guess I had better warn
the captain that his vessel is about to fall apart under him.<grin>
