Hey Y'all; Thanks!
Just back home from Saturday morning meeting of our local creative writers group then lunch out here in our 3 block long county seat farm burg's downtown.
Probably the simplest thing to do is post links to the couple of Flickr albums, one featuring the 2ft long first sub and one featuring the 3ft Typhoon-inspired one.
The 2ft sub was built from, well, more like inspired by, plans in a 1970-something book my parents gave me while I was in 4th grade.Only took me about 30 years to get around to finally building the sub but that allowed some significant improvements to be made.The takeaway there being that sometimes, a couple decades of procrastination does pay!
The 2ft original & a more military looking build for a neighbor,

Sub is dynamic diving.Ballasted to float with deck awash.Hull is hollow and free flooding.
About 300 winds will get it the length of an Olympic sized pool.Propellor is from a 2005 era Traxxis RC deep-vee which appears to now be out of production.
Periscopes are brass and copper tubing from K&S, they go through to hull interior.And as an added bonus at no extra charge they often give off a trail of bubbles as sub dives.
A couple photos are of the,
"There’s what happens when you have cats who shed like mad and you don’t dust a thing for about a year and a half. 
" category.
The figures are Revell Germany 1/72 scale soft plastic U Boat crew.
Handrail stanchions are long out of production HO scale locomotive parts from Athearn's 'blue box' era.Handrail cable is beading wire.Grab irons up side of conning tower are miniature staples.Hatch is a googly eye with HO scale boxcar brakewheel.
"Weathering" is actual repairs of either physical damage or damage to paint.
Testors Dullcote is sometimes affected by chlorine saturated swimming pool water.
Dive planes are brass sheet soldered to brass rod through a brass tube.Friction from the seriously annoying label adhesive was used to benefit.Forward planes have sometimes gotten bent from collisions with pool walls.Aft planes had balsa "inverted airfoil" to fine tune buoyancy aft.
In a nod to the solder strip used as a keel and ballast in the 1970-something plans it has a keel of 1/16 by I think 3/4 brass strip set in to a slot cut through 1/2 inch thick bottom plank.
Ballast was added to pockets chiseled in bottom plan exterior via steel shot super glued in, then puttied over.
Rudders are sheet styrene over brass rod like sandwich bread over a frankfurter.Hollow was filled with baking soda soaked with thin super glue, a layer at a time to reduce heat the curing glue gave off.And when you set rudder, YOU GET RUDDER! This thing has 'rudder authority' like you wouldn't believe.
Oh, speaking of super glue ...
Hull surfaces inside and out were hardened via being soaked with really thin super glue.The interior was done, then painted white, before deck was secured.
The cat's name is Georgie.
Power is 2 loops of 3/16 tan sport rubber from FAI Model Supply.
Last year bought some 1/8 inch to see difference between 2x 3/16 and 3x 1/18 for power.Haven't run test yet.

Okay, that's about it for typing, my hands are hurting.
Will tell about the twin screw beast later.
