Re: [PSUBS-MAILIST] Building a psub for sale?

Herve - I think we are mainly on the same line..

I agree - the question is : 

Who is the user, 
who is the builder,
who is the manufacturer ?

The idear was to change the status of the builder - in this case a
friendly,
helpful non-professional Psuber from builder to manufacturer. And the
status 
of the user to builder. 
Than the friendly Psuber will still responsible as manufacturer - for
example for 
his weldings - but not for a general accident (hatch blow open 
by overpressure in 3-6 feet deep by using the wrong vale - boat sunk)
because the 
person responsible that the unit was assambelt and the vale was marked
is the user.. 
He can be this status by just doing the logistic assambling work on his
desk. 

Many shops here in Germany sells the bycyles as "selfbuildings kits"  -
means 
one single nut - which secured the helmpipe was unlooked. If you
purchase this "kit"
and secure this nut - you are the final "builder" of the hole unit. 
Yes - they are still responsible for all parts they manufacture - but
not for 
using the unit. Or accidents during normal using the unit.

And each of them is a prototype - as most ships are.. You will find
some failtures on the first test drives..

Wau - great idear ! But were can I purchase ignition proof electric 
devices like radio transiver, sonars, GPS, electric room heater, 
generator, starter, hydraulic pumps, mainswitch boards, microwave, 
waterboiler, speakers, lamps, compressors etc.. - and who pay that
bill.. :-?   

I will storage the oxygen bottles outside the hull - and the helium, air 
and most of the hydrogen bottles inside - but a catalitc hydrogen
converter
in the top of the pressure hull seems a good idear.. a atmosphere sensor
for oxygen, pressure, hydrogen, helium, CO2, CO, etc will be also
installed
- and a big red flash lamp - and a destroyer-sound claxophon (Boschhorn)
which can awake also dead persons.. - if one or more of the senors shows 
something outside the borders.. 

Herve - what do you think about a label inside the sub near the helm
like : 

"This unit is a toy and can be only operate in LLoyds 
AND ABS certificate swimming pools newer than 3 months 
and not deeper than 6 feet and with a security crane onshore."  :-)

If the user agree that you build the sub for him - with this label 
- how is responsible if he use it in the open sea or in a 
7 feet deep lake ? 

see you - Carsten
