build it as 1 piece for now so when test fitted onto the boat, the shelter will fit tight to the boat's deck & will be level. cut the openings out later. do you have a dremel tool or similar with a deburring tool? build the outside walls 1st with the bottoms fitted to the shape of the boat deck so no gaps appear. figure out the height difference between the vertical walls & top of roof. are you going with solid walls all around besides the openings or do a pole framework on the backend of the shelter as shown in the bottom picture?

how big is that boat & do you have styrene sheet plastic with a thickness between .02" to .04"?

the angled sides for the base of the superstructure, is it a separate piece(s) or part of each printed hull segment? the reason of asking is the ledge between the hull sides & the angled sides for the base of the superstructure, is it supposed to be there or not?

maybe expect a few phone calls/emails from those jealous visitors as wanting a copy.

ran into that problem with the unintentional side venting when i modified a single engine Honest John missile( about 4ft in height) with 1 D series rocket engine to a 3 D series engines to get more height. i made a cone to fit over the combine tops of the 3 motors that goes into a tube leading to the parachute & removeable nose cone. so when the ejection charges of the 3 motors went off, the charges goes thru the cone into the tube causing the nose to pop off & deploy the chute to bring the whole rocket hopefully safely to the ground, supposedly. it did not work like that but worked like how the real Honest John worked. it was a night launch so i connected the voltage probe so that it's light came on, inserted it into the nose cone of the rocket so it glowed thru the green paint of the nose cone & launched the rocket. you can see the light of the nose cone & the 3 rocket motors push the rocket vertical for a few hundred feet til the motors stopped running then see the whole rocket with the light on in the cone come speeding down to the ground a few hundred feet from the launch site were it impacted the ground hard & destroyed the rocket. the parachute did not deploy because when the 3 ejection charges went off into that cone, instead of going thru the tube to the parachute, the blast from the charges bounced of the inside of the cone & vented thru the openings caused by the shape of the 3 motors in a circular shape with the base of the cone venting backwards not forward so no force to pop the nose cone off & deploy the chute. if i had plugged those openings then the rocket might have worked properly but we will never know. when the door is closed when launching your rocket, is the door lid causing the rocket to go on an angle as the lid brushes against the rocket as the rocket leaves the silo whereas with the door already open, the lid does not brush against the rocket as it leaves the silo therefore the rocket goes vertical?

how far did it fly & was the flight straight?

it is the center of gravity & center of mass you have to worry about as they determine if the rocket flies straight or spin out of control. are you lining the inside of the missile launcher with something that is flame resistant as that rocket exhaust will most likely burn thru the bottom of the launcher into the inside of the model ship causing it to burn or become a submarine?

Propeller shafts of WW2 warships were generally painted to protect against corrosion and marine growth, rather than left as bare metal. The exposed sections of the shaft that were underwater were typically treated with the same anti-fouling paint used on the rest of the lower hull.

remember to paint the prop shafts the same color as lower half of hull as the shafts were never left as bare metal but painted.

have you test fired 1 of those rockets even using Estes igniters to see if fly straight up without spinning out of control due to incorrect location of center of gravity as i've seen that happen & 1 guy got hit in the chest by his own rocket? use to launch model rockets back in the late 1970's while in high school. still have some rockets & motors.

if those are ciws mounts on either side of the ship's funnel, i hope they change the locations with 1 above the bridge & the other ontop of the hanger as current locations do not have a good arc of fire do to ship's structures interference of arc radius.

you are welcome.

what time period of the war does the model represent as appears to be 1943 or later?
