Re: Naturally Durable Wood--was SOG foundations

[Subject Prev][Subject Next][Thread Prev][Thread Next]
One of the longest running experiments in naturally durable wood life
testing floats in Boston Harbor - USS Constitution.
Keel, planking and knees - white oak
Frames and Diagonals (the ships skeleton) - live oak hand selected in pretty
much the right shape to start
some of these are original even today - the live oak is quite durable

or at least subject to  interpretation.



That wood be Redwood as a sill plate material.......costly at todays
prices.

Could also be cedar.  Or, arguably, white oak, locust, or walnut.  In
some locations, white oak actually can be had pretty reasonably.  The
best is probably cypress, but I don't think that's commercially
available anymore.  And, it's awfully soft--even softer than redwood.
