i thought i would post this here as the members here seem
to be more into scratchbuilding here then on other forums:pc:
my thought are to build a semi scale verison
i'm thinking about useing blue foam to shape the hull then fiberglass
what dose the bottom of the ms3 look like
huh.gif

rough size so far 12'l X 3'w X 1.5 d
for flooding i'm thinking of useing drill pumps
all ideas welcome

This handy little pump can be used with any drill with a minimum speed of 1200 RPM. Excellent for emptying overflowing dishwashers, washing machines, aquariums and clogged sinks. Use standard size garden hose on each side. Inlet and outlet are clearly marked.
Ideal to pump water or oil with your electric drill
Multi-purpose pump
Maximum pumping capacity to 225 gallons per hour
90 day warranty
Minimum drill speed 1200 RPM
Thermoplastic construction
Perfect for emptying overflowing dishwashers, washing machines, aquariums, and clogged sinks.

i'm thinking 3 sections that bolt together at pond side:mrgreen:
how would i go about sinking her to the loading level and
not to the total sinking level??? the pumps above seem like
they should pump enough water. i was thinking 4 water chambers
two in the front and two in the back
 
Hello Bigford,

I'm also into submarines, the words 'watertank' and 'sinking' usualy wake us up ... :D

You would need a seperate filling system for each tank to be able to ballast her correctly and evenly, like Danny already mentioned. Then you can allso play around with the ballast when lifting things. That means four independent pumps, or valves. Pumps would be better to work with I think. And a water sensor cut-off on each tank to prevent overfilling them. You could even make the leveling automatic by installing one or two electronic water leveling systems, like we use them in our subs to keep them horizontal while underwater. You could also fit a sensor system (watersensor, floater) to measure depth, and add or pump out water to correct depth.

These drill pumps generally use a flexible impeller for pumping the water. These impellers generally have a lot of friction with the pump casing, resulting in a low pump efficiency and a high torque. These pumps may not be able to work in both directions equally well, but this feature may not be required. Depending on the discharge required several pumps may be usable, but it is not true to scale to submerge your ship in seconds time scale.

do you think a few windsheild washer pumps would be better??
also think of cutting her lenth to 8' x 2' feet instead of 12'x3'

the hard part i think will be shaping the bow :mad:
here is a pic of my 1/50 smit rotterdam i'm working on now

Windsheild washer pumps would have far to less capacity. I'm thinking more in the lines of camping waterpumps found in caravans. Your average windsheild washer pumps will pump 2 liter per minute, as caravan pumps go to 10 liter per minute or more. But they can only pump one way, so the filling of the balast tanks would be by valve, and emptying by the pump(s). If you have an open air connection on the top of the tank a cut-off mechanisme would not be required.
