Re: [PSUBS-MAILIST] Wooden Submarine design for discussion
Pat: et el...
Thank you for taking a look at "my" design. It was
my thought to make this Psub out of wood primarily because I felt more people
could potentially work in it. Though I have done a lot of welding (MIG, TIG and
Stick, Oxy Acetylene...) in my area of professional work (museum exhibit design
and construction) I also have done a lot of wood work.
I wanted to see what others people's ideas were in
regards to the design? I do realize that there will be significant need for
additional weight added in order to control buoyancy and draft. I was thinking
about using metal tubes (pipe) filled with some weight such as rebar or
concrete or recycled lead. I feel confident the hard points for these weighted
cylinder could be incorporated into the wood structure and one or more could
function as my drop weight in case of emergency.
You will note that I included two sizes because of
my own concern for displacement and completed submarine weight.
Any additional comments or concerns would be
greatly appreciated. I would like to open a dialog with other people who are
interested in this idea of a "modern" wood Psub.
Sincerely,
John Gaertner

Hi John,
Without running the numbers: she looks like she can be
made to balance, but if this is a dry sub, she'll displace a few
tons. Wood being relatively light and buoyant, there's a good chance the
waterline will be so high your prop will chop air on the surface; and where's
the weight required to submerge? You could stuff her with lead, but that
will take up a lot of space and could lead to a structural failure.
It's a nice design. Why not build it in
steel?
