[PSUBS-MAILIST] Threw hull calc's
I have a piece of stainless steel bar stock that is 31/4" Diameter. I have
to drill a hole in the center of it that is roughly 13/16" to accept a 3/4"
Diameter threaded penetrator with a threaded length of 3/4" long. My hull
thickness is 1/4" (K-350). I am under the understanding that you need to
replace the amount of metal you remove from the hull with equal or grater. I
would like to be able to slice this SS bar stock to 1/2" thick and weld it
into the hull so that would leave me with 1/4" on the inside to put a nut
and washer on. My concern is that it may need to be thicker to calculate
out. I can have the company extend the threads at an added cost but would
rather not if possible. Can someone tell me if I weld a piece of 3 1/4" dia
bar with a 13/16" hole in the middle of it how thick it should be?
Thanks
Rick P

And the same from me. Now all I have to do is live up
to all the kind words.
And by the way, that rock star thing? I'm sure he
was talking about the rocks in my head. Definitely.

PSUBS.ORG is pleased to announce the recipients of
commemorative and
recognition awards for 2009. All candidates are
nominated by their
peers from within the PSUBS community reflecting admiration
of
excellence and contributions that the candidates have
demonstrated to
achieve a nomination for an award.
KITTREDGE AWARD - Emile van Essen (Eurosub)
The Kittredge Award is named for Capt. George Kittredge and
is presented
for excellence in overall design and/or construction of a
small
submarine. Emile designed and built a small 1ATM
submersible named
"Eurosub" which has been described by PSUBS
members as "beautiful",
"functional", and "raising the bar for all
potential sub builders".
BUSBY AWARD - Vance Bradley
The Busby Award is named for R. Frank Busby and is
presented for
excellence in technical writing or documentation regarding
the design,
construction, or use of small submarines. Vance was
recognized by his
peers in the submersible community for providing clear,
first hand
information about technical and operational topics on the
PSUBS mailing
list and as a person who has been described as "one I
look up to for
experience". He has spent thousands of hours
underwater over a decade
of offshore work, qualified as pilot for nine different
manned
submersible vehicles, and was one of the most senior of
Intersub's
pilots during the fevered construction days in the North
Sea.
LINK AWARD - Emile van Essen
The Link Award is named for Edwin A. Link and is presented
for
excellence contributing to oceanographic research,
exploration, or
discovery using a personal submersible, or the
design/construction of an
innovative submersible component. Emile receives this
award for his
participation with historical and archaeological survey
work using his
submersible "Eurosub" on the sunken vessel
"Giuseppe Garibaldi" (at 122
meters) for documentation by Croatian historians and
archaeologists.
BEACH AWARD - Dean Ackman
The Beach Award is named for Edward L. Beach and is
presented for
non-technical writing or documentation that promotes
personal
submersibles. Dean receives this award for excellence
in promotion of
both personal submersibles and PSUBS.ORG. After
providing an interview
with a local paper regarding his newly built submersible,
Dean was
contacted by the USCG who had heard about PSUBS but never
seen a small
home-built submarine. Dean arranged to meet with
Coast Guard personnel
to let them inspect his submarine and discuss the details
of his
project, as well as the mission of PSUBS.ORG. Dean
received a Coast
Guard "thumbs up" for his submersible which
reflects well upon our
organization and our desire to build good-will with local
and federal
authorities.
SPECIAL RECOGNITION AWARDS
These Awards are presented to individuals who uniquely
contribute to
PSUBS.ORG or promote personal submersibles in a manner that
does not fit
within the more narrow scope of our Commemorative Awards.
Kyle Edlund - Kyle receives special recognition for the
effort he has
put into testing an acoustics anti-collision unit built by
David
Bartsch. Kyle has performed multiple dives with the
unit in his K-250
submersible and returned detailed reports, including video,
regarding
the performance and user interface. These reports
have been very useful
to members who have an interest in this particular
anti-collision unit.
Jay Jeffries - Jay receives special recognition for his
contributions
focusing on safety and operational procedures, and his
expertise in
marine architecture. As we progress and grow as a
group, safety has
always been a major focus and will continue to be an
integral part of
that growth and how we and our sport are perceived by the
general
public, associated industry, and regulatory agencies.
Jens Laland - Jens receives special recognition for his
important
contributions which have provided a vast assortment of
photographs,
technical documents, and pointers to authoritative
references. Jens is
described as " having a great wealth of
knowledge" and "a willingness to
openly share that which he has collected with those that
simply inquire."
Congratulations to all the 2009 winners!
