J.T.

The U.S. WWII submarine shaft bearings were fabricated from lignum vitae, using "chevron" packing in a mechanical seal. Depth charging played havoc with this seal, but most boats survived as long as the 6-stage drain pump was operational.

The main advantage of using this oily wood, was quiet shafts while submerged. It is a very durable material, as long as it remains underwater.

Later,

ROBERT M.
