[PSUBS-MAILIST] Welcome Ross

Welcome to the group Ross, you will find the following links just a little bit helpful.

Five-O was a favorite of mine as a kid and any aficionado remembers the episode when McGarrett was dropping concussion grenades on two bad guys in a PSUB. Hawaii is nice but too cold for a guy from Miami!

    welcome

    i assume that you have some wants in s sub and a budget.

that where you start.

ambient or 1atm

how deep

how many people

how long duration

what type of view ports/ this point is really!!! expensive

will it be certified.aslo expensive can add 100 grand to the project.

look at the k350 for a good platform to start from

remember that everything is a tradeoff

the cheapest way to 1atm is to design around a depth that you can bail out from if you have a problem. with limited duration 2to3 hours. this allows for a small scrubber and a small o2 system. very simple system yes you have trashed your gear but you are still alive.

    the hull expense is about 20% not including view ports and penitrators. propulsion systems are approx 10%

view ports can go up to 50% of the total cost.

    the expensive systems come into play when you start talking about 72 hr emergency duration, surface comms, video, tracking devices, and hyd manipulators.

    i have a design for hyd manipulators that can be built for under 2000 $ if you ebay some and get creative with others.

that is two arms

Hello everyone,

I just joined the group. My name is Ross Donato and I live in Ewa Beach, Hawaii. That's on the South side of the island of Oahu, West of Pearl Harbor and Honolulu. I am a certified scuba diver but I prefer free diving and spear fishing with a Hawaiian sling. To me, that is more of a challenge and more rewarding.

I have been reading your web pages and looking at the pictures for more than a year, ever since a friend who has connections with the University told me about you. As you may know, UH operates small deep diving submarines and has made some important finds like the Japenese minisub from World War 2.

So, a little bit about me. I have worked with machines and tools for most of my life. I worked on mostly cars and boats, like that. In fact that is what I do for a living, but it is also a hobby for me. And! with the big four-oh just around the corner I was thinking "why not build a submarine?" So I am here to learn what I can, and I will help out where I can, too.

I see you talking about the Rhino CAD program. I have used it before and it is very easy to learn. Even better is you can get it for free to try it out. Use the link Julian gave below to get to the Rhino home page. Look at the top and see the word "downloads". Click that and you get to choose "Rhino evaluation". That's it. You can download it for free and use it. I think you get like twenty-five saves or something like that before it quits. But then you can always download it again. It is a good program, simple to learn, and free. I hope this is of some help to someone.

So, I just wanted to introduce myself and let you know of my interests. If there is anyone willing to help me ! get started I will appreciate any help I can get. I think I understand how a submarine works and I can draw my designs but right now I am having trouble trying to figure out where to start when designing one I might build. How do I know how thick the steel must be, how much it all must weigh, and like that?

Are there any books that explain how to figure that out that are not only for the slide rule crowd? That would help me a lot to start. I am a high school graduate and not too bad at math and science but I am no Einstein when it comes to that. But I hear it isn't really so tough to learn and you don't have to be a big math whiz to do it.

So, I throw my net and see what I get. Any help getting started with the numbers, you guys out there?

Mahalo in advance.

Ross Donato

Catia V5... Solidworks... Autodesk Inventor

But, they all WILL bankrupt you. Autocad Inventor I believe is the cheapest. There are some pretty good 2D Cad programs you can get for free if you have no need for 3D. A good one I used was calle! d "Draft IT". If you simply need a good 2D drafting program I wouldnt bother with Autocad, might as well get a free program. For 3D, nothing beats Catia, that's why pretty much our entire modern fleet of military ships and planes are built with it. Alas, it's a $14,000 program.

Biggest problem with design software is simply the training involved. To give you an idea: certified Catia drafters make starting salaries of $65,000+/year... just to draw parts.

The best "alternative" to the expensive 3D Cad software is "Alibre". It's actually free for the most part, but a fully licensed version is still only like $300 I think. It's a newer system but the support is there simply because of the free "trial". Also cool because it's designed to be used online ! so you can collaborate with other designers.

The time has come to graduate from MS Paint and Word as my primary design software.

Any suggestions? Try not to bankrupt me though! :)

Thanks
