Ian. I recently saw a documentary about some of the bridges along the
Calif. coast, and even though the re-bar isn't directly exposed to salt water,
there is a problem with it rusting out while inside the concrete of the bridges.
It has to do with electrical activity. Anyway, one of the bridges was built
using stainless re-bar and it is still like new after 70 years, where some of
the others have required extensive repair because the concrete is spauling ( sp?
) around the re-bar where it has rusted and actually popped the concrete.
I don't know how much re-bar is going into the hull, but the cost of
stainless re-bar is several times that of plain steel, but still cheaper in the
long run.
I received my steel hatch back from the machinist today. He planed the ring
and cut the groove for the ''O'' ring. Hope to have it installed soon. I'll add
some pictures to my frappr site when it's on.
As for a drink together, that sounds good.
Are you planning on a trip to Wil's to see the progress ?
Have a good new years. Frank D. |
