I would like to give a very special thanks to the
sub owners that brought their subs to the convention. Seeing what has been done
was my main interest in attending the convention. And I congratulate each one
of you for getting it done in your own way. My background is in aviation,
both civil and military, being licensed as both as a pilot and a
mechanic and I was a member of the Experimental Aircraft Association
for 20 years. The EAA publishes a monthly magazine that contains articles for
the most part written by other amateur members .I have seen articles on
how to build your own autopilot, how to overhaul a Volkswagen engine for
airplane use and many other technical articles on critical equipment. These authors are not doctorates in their
field; they are just enthusiasts willing to share unique information with
other hobbyist to enhance the enjoyment and or safety of the sport. I am sure
there are many of you that have that kind of special knowledge that could
be posted on the psub web page for the benefit of us
all. I am considering building a sub, but many things enter into
that happing. 1. dedicate an adequate work space 2.learn basic CAD
skills 3.refresh welding skills 4.educate myself on ABS standards 5.
purchase more welding equipment.6. find a machine shop willing to work with
customer drawings. 7 find a couple dozen suppliers that will sell 1 or 2
each items to a retail customer. 7. in my spare time read Dr Stachiw's
book and learn how to test acrylic view ports. 8. convince my wife how much fun
we are going to have working 10-12 hours a day on a large steel tub. 9++++ I'm
sure I will find out about the time I start my first assembly.
What I'm saying in comparing psubs to
the EAA is that the EAA builder must do every thing that I just listed
above, but he has the additional help of fellow builders or knowledgeable
individuals who are willing to share. I don't follow the logic that I
must design electronic circuitry for a home built system just because
misuse can kill me.In building an airplane If I misuse a cable swaging
tool or fail to test a control cable I guarantee you that I will die
of something other than old age,but I still don't think I have to build the
swaging tool. put the design on a public form, explain what the
circuitry accomplishes, how to test it, tell us the" what ifs" and leave it up
to us to use or not . We build these things by our hand if we die we die by
our hand. If it was any other way the kit built aircraft industry would not
have lasted this long. What I need living in southern Arizona is sources of
supply, examples of how things were done that worked. I have reviewed the K350
drawings and I suspect that many of the vender supplied parts are no longer
available. What are the work arounds. On the psub web page there is a design
page that has gone nowhere. Come on tell us new guys of a solution that you are
proud of.
