rob

thank you for having the decency to reply to my posting

yes you are right i'm sure as you say i'm taking my frustrations out on the

many people who subscribe to psubs

i live in the Uk and i'm sure i am in the minority regards people who would like to build their own submersible, it's not like i can call up a buddy and talk design or fabrication,

but here just try approaching a company to supply you with a pair of end caps for a pressure vessel

and you are into very dark waters

"what do you want them for "is the usual question needless to say i get an adverse reaction

i do have extensive experience in engineering and fabrication .

i run two manufacturing companies and a retail shop,but like a lot of people

we are experiencing a downturn in business.

thus my hobby is relegated to the shelf

it's very hard to watch you guys get on and do things positively.

carsten is the best example of drive and determination and has given us all a

very large kick up the arse  when it comes to getting on with the job

the man deserves a medal in my book.

also yourself with the bionic dolphin project

please dont think of me as the guy who just grinds on about his lot in life

i'm very positive with a will to succeed

but the ping pong balls thread just left me cold .

i have blown my own foam for sufboards (yes i have photos)

which here in UK is somewhat extreme .we could buy surfboard blanks  from america

but the price killed our product so we built our own moulds  and blew our own foam

it took time and money but we did it . this might mean jack xxxx . but at the end of the day

we put british surfing on the map.

i relate as a lot of psub members do to the practical mechanics article about the diver propulsion

vehicle that we can now buy plans for on the psubs site.

i read the article many years ago as a boy and it has stuck with me

to this day

what i'm getting at is the thought that we are obsessed with technology and refer to a

peice of software to sort the problems out rather than grass roots  math and design criteria

along with hands on engineering (welding .lathe work etc)

kittredge epitomises this ethos in the fact that he has produced the goods moreso than any psubs member .

you refer to the new zealander william hamilton, we also have such innovative heroes as frank whittle

who also dedicated his lif to the realisation of the jet engine

so yes i do understand the need to explore engineering diversities whether good or bad to 

a final conclusion.

and i praise  all those like minded souls  in their quest to succeed

also yourself with the bionic dolphin project

regards roger rabbit

It sounds to me like you are taking your own frustrations of your projects lacking progress out on the group members who choose to share and discuss some of the more outlandish design ideas. Is it really that much of a burden on you. You're not obliged to read every persons contribution in their entirety. I devote most of my spare time and budget to my dolphin project. I too have the frustrations of running my own business. I know what the real ratio of construction time to real testing time is (about 100:1 presently, which is actually a vast improvement from last year). But I also remember when I first decided I wanted to build my own submersible creation. I remember the many far fetched ideas that I ran through, from bending fuselages to internal vectored jet thrusters. As it turned out most of my finalized power choices were far more conservative than those initial dreams of revolutionizing modern technology, but I have the utmost respect for those who choose to pursue the more unreliable and often least cost effective alternatives. Most will, as I did, eventually bow down to the impracticalities and their own dwindling budgets, but some like the great William Hamilton , a fellow New Zealander and perfector  of the modern jet pump, chose to stick by an idea that had been tested and had failed for over 100 years. Regardless of the odds of success, I think it is an important stage for every builder to go through. How many people to you really think are going to want to build submersibles if you deny them the possibility of contributing new ideas, regardless of whether they've been discussed before or you deem them unworkable. I look back at my old sketches with great joy seeing how far I've come since then but also how cynical I've become as I've learnt more; a fact which I am not always proud of. I say we need to keep the spirit of innovation alive and if you're not interested just click to the next e mail until you find what ever it is you need to hear.
