Chip,
I hear what you're saying.
Us guys that are bound and determined to make their marriages work often have to
put their prides on hold, step back, and decide what is important. The
situation with the sub is a little different. I understand having to
justify several thousands of dollars of the house hold budget for some pipes
welded together that will sink in water (no shit). She wants to know
roughly how much, I can appreciate that. I'm just thankful she's the
responsible one.
Since we're ordering, I'll take a
large double, double.
Myles.

Hi, Again . . .
Yeah, trains and prairies go hand in
hand :-)
This is my first sub. I'm keeping it
simple with straight electrics - trolling motors and lots of
batts.
The Typhoon hull form I will be using is about
as cheap as I can get it. Making it a dry ambient boat eliminates
the complexity and expense of a one-at boat and yet provides for beautiful
panoramic underwater views. Plywood for the simple curves is dirt
cheap. Cockpit is heavier ply - cheap. Fiberglass & epoxy,
not so cheap. Canopy less than $500. Seats - cheap.
Motors less than $600. Batts about $500-$600. Gauges
simple. Air tanks will be rentals. Regs second hand. Will use a
second hand boat trailer for hauling to the boat launch. Tuxedo rental,
espresso maker and martini glass to impress onlookers
- priceless.

Rick,
Im a bit of a train guy as well
as sub guy so yes, I was aware that locomotives were in fact diesel /
electrics.
I am leaning towards the diesel
/ electric method in an effort to keep things as simple and reliable
as possible. I see shafts,bearings and clutches as sources
of mechanical breakdown. In the end, the cost would likely ballance
out anyway if a person was to factor in maintenance and replacement of
these parts. The thought of messing around with them once they are
installed is not appealing, pretty tight quarters in there.
At this point, I'm still in
"dreamer / planner " mode, wondering if I can get the funding together to
make something like this happen. There are many other factors that
I'm thinking about as in simply being able to transport and launch a sub
that weighs about 7000 lbs. (but that's a whole other topic).
I need to come up with a financial proposal for the board of directors (my
wife) which is what I'm trying to figure out.
By the way, I'm about 3 hours
south east of North Battleford. Quite arguably as far away from the
ocean that a person can get. .....I'm looking at making
the sub for fresh water lakes anyway.
Thanks for the
response.
Myles.

Hi, Myles - anywhere near North
Battleford?
Thanks for all the warm sub thoughts.
You have now entered the hallowed halls of the
I-wanna-dive-around-the-world-in-a-sub crowd.
Rather than re-inventing the wheel, I'd opt
for the diesel electric model myself and for much the same reasoning as
you presented: simplicity.
It works in subs and locomotives well
enough. Many people don't realize that locomotives are not diesel
operated they are electric. Those chugga-chugga sounds are diesel
generators.

Hello all,
Like all of us here, I have
this wierd fettish with subs. U-Boats are my
"thing". (Peter Madsen is cool in my book) I have
dreamt of building one for years but always thought it beyond my
scope. That was until I stumbled upon PSUBS.org. By tuning
into discussions and reading everything I can get my hands on, I am
coming to the realization that "normal / average" (perhaps that isn't
the right term) people build these things and not some excentric
millionaires or something. (you know, the same guys that take solo hot
air balloons around the world). Over the period of several
months, my confidence has grown to the point now where I tell myself,
"I could build one of those." The
group here at PSUBS is indeed "special". I admire each and every
one of them for following their passion, whether they bring it to
fruition or not. The guys that actually get something in the
water have really accomplished something unique.
Does anybody have any thoughts on direct
drive diesel / electric propulsion ? I am still contemplating
whether that is the way to go, or whether a guy should use the diesel
/ electric as a generator to power the thrust motor ? I like the
direct drive method for it's added efficiency, price (Only have to buy
one motor/generator instead of two, one generator and one
thruster) and generally more "U-Boat" like, but I am wondering if
the engineering required to get the shaft connected in line with the
clutches and bearings through the pressure hull while maintaining
pressure hull integrity is worth it. (what does it take to
seal that shaft ?). I also have concerns with the mechanical
dependability of the two clutches that would be required.
(Could be a real bugger to get in there for maintenance and
replace). The other way would simply mean connecting an external
electric thruster to the battery source that is being charged by the
diesel which I believe would be easier to do. (Am I right here
?).
I'm more interested in
building a 1ATM U-Boat resembling sub that has decent surface
performance rather than something that will dive deep. I'm
aiming for an operation depth of 35M.
Thoughts / opinions on propulsion
?
