Re: [PSUBS-MAILIST] OSS
Hi submadmans, based on the Kittredge design as startpoint
I would like to see:
- a doubleseater, 100 % more fun for 15-20% more cost.
- a warp around acrylic cylinder in the tower like the
the Pauls S101 and S102 have, so we can combinate the
good view of the dome Boats - and the good freeboard of the
tophatch boats versions..
- a much better outline hull, special at the bow and stern area -
but maybe no cover in the hull area. Bow like S101..
- a bolted stainless steel frame stern endcap with a seal so the boat
can be completly open for building and later for maintance.
On the stern cap for the reason that we can design a extra section
"Dieselsection" which can be added as plug in modul for the boys with
the long lakes in there garden.. same flange can be used for a diver
exit chamber modul - or for both moduls..
- all plans also on a DXF/DWG 2D CAD system - special the metal cut
sheets in a form that you can give a disk to a plasma/higwaterpressure
cutting company and all parts can be cut by CNC machines to make the
building
quick, easy and cheap..
- size mind 2 and max. 3 ts so can be carring behind a light truck.
- in steel it should be not a big deal to design it for 200-300 meter
(650-1000 ft)
A figure of 20-30.000 USD is probably right..
After the general defintion phase - the design team should be
reduce to an expirence and small group - present just results.
"20 boys into a small galley making something will be a nightmare of a
dinner.."
It must be a clear non commercial project - or I will not spend any time
on it.
It must drawn by hand or at a 2D CAD programm - or I am out for personal
reasons.
I manly will investigate time in this project if I found something looks
unsave.
If OSS is a sucess or not - depents only on the campainer/moderator
not on the technic..
Be carefull Warrend - Campainer for this is a real hard figure.. :-)
Warrend .. a question - many years at Psubs it was a good pracise to
introduce
yourself.. age, pracise, dreams job etc.. have you done this ?
(Sorry if I maybe I miss that. )
best regards, Carsten
