Re: [PSUBS-MAILIST] FEA Work on Acrylic CT for KLH-500
Hi Jon, You make a convincing argument. This summiting material and ideas
is a tricky business. ;} Averaging about 10K visitors per month is busy.
I don't know if we can consider are selves to be in an obscure hobby any
more.
Cheers,
Brent

Brent,
Just trying to provide you with some constructive criticism here.
The FEA work you've been doing is interesting, and because you are the
only one sharing such data, it's also very valuable if it was done
correctly and your results are valid. However, that's the big question.
I suspect your sharing the results are not the problem, but the
presentation you use to share it. You tend to present ideas and
information as factually correct when a better method would be to present
them as "findings" and ask people to analyze and confirm your results to
make sure they are correct.
Your statement about the group knowing you are not a professional analyst
is a bad assumption. You only interact with about10% of the total number
of people signed-up to receive email from the group. In reality, the vast
majority of people who receive your mail know nothing about you. This
goes exactly to one of Jay's points in that the drawings you are providing
look very professional and without proper context they could be
interpreted as professional results by people who do not know anything
about you. You also need to keep in mind that we average 10k visitors to
the web site each month who can view your email through the archives, and
they almost certainly know nothing about any of the contributors.
What you say matters because somebody at a later time could be making
assumptions about your assumptions. That doesn't mean you can't provide
interesting data like the FEA results, or suggest innovative solutions to
old problems. However, it does mean that having proper context will
result in a much more receptive audience by those who have expertise in
the subject you are discussing.

to the group. One doesn't need to be a professional FEA analyst to have
good input. This group knows I'm not a professional FEA analyst. They
also are well aware by now that they are responsible for there own
submarine designs, and what data they choose to use to design there subs.
I could choose to only send this material to a select few I know and/or
suspect would have good input. But there are many in this group that I
don't know at all, and others I do know that have a wide array of back
ground experience in so many things, that I don't wish to miss out on
there input. Besides it's been said before, why should the select few get
all the fun of looking at different proposed designs?....*
