[PSUBS-MAILIST] New submarine

Scott,
I make 1.23" thick for a 72" ID sphere 516-70 to that depth, sea water. 
That was on the "free" Under Pressure program. It should be somewhere in the ball park.

Would anyone on psubs who knows how to use CAD run a pressure test on a simple 6' sphere with ASME 516 grade 70 steel, then again with HY-80? What are required wall thicknesses to meet crush depth of 5709 feet (2543 psi). If you have time maybe even a 48" cylinder with ribs. 
On a lighter note, Alec and I have been talking about hard to find things that I can make for psub members with my plasma robot. I am going to attempt making a manipulator arm kit that will be inexpensive and very functionable for our subs. I'll post progress as it comes.
 
Thanks,
Scott Waters

>>Scott, 
>> A 3300 fsw capable sub will more then likely require that the pressure hull be fabricated from HY-80 or HY-100 . I can assure you that working with either of these two alloys is not for the faint of heart or wallet . I am sure Phil Nuytten can shed some light on this subject . Idabel was built from parts scavenged from some well know subs. If memory serves me correctly the acrylic dome and a HY-100 sphere came IUC's Beaver . The other sphere came from one of the Perry boats .( Vance if I have this wrong please set me straight ). If you get lucky and find some similar bargains you might hit your budget of $100 to $200K . If you have to start from scratch I think $1 to $2 million would not be unrealistic considering the learning curve you will experience. The level of quality control required to work with HY type alloys is something to behold . I am not saying it can't be done it's just that you might make a serious dent in your inheritance .

With every process of welding available, robotic plasma cutting and design software, a 8,000 crain/lift, metal lathe, hydrolic ban saw with coolant, and about every tool anyone could want, it makes life a lot easier. When I started my K-350 back 5 years ago I was a kid with a set of blue prints and a goal of one day having a submarine and that's it. I didn't know anything about submarines besides they used "ballast" to go up and down. I didn't know how to weld at all or even knew what a metal lathe was. And the only tools I had was a small tool bag with basic stuff my dad had given me from our family hardware store as a graduation present. The reason I don't want to build a 1000' sub is it is not a big enough goal. I need something that is the difficulty level of starting with nothing and no idea to a k-350. I compare a k-350 to a 1000m (3300') sub with completely capable manipulator and
 tooling with very advanced technology to be a similar difficulty level and step. I also want to push the envelope for psubs about what we are capable of. Combined we have so much knowledge that if we all worked together, we could be producing ideas and inventions right up there with the big dogs. Hope this helps with everyone understanding my vision

I built my K-350 and it was $40,000 after all the gadgets were put in and I hired out alot of work because I didn't know how to do it at the time. I did a comparative analysis on weight to dollar. My K-350 at $40,000 and 4,500 lbs is comparative ofa 10,500 lb sub would be $93,333 if you add more for acrylic costs my rough math seems to jive with the $125,000.

If I were planning to go beyond 1000 feet, I would be looking to Nuytco, SeaMagine or Triton but of course cost is then a major issue again. Does anyone know about how much Karl spent building Idabel? ~ Douglas S.
