[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!
