I',m sorry, but are not able to upload this and another two in an apropriate size. Keep trying

A bit blurry. Maybe you could repost it.

Hi. AS I've been requested about how I've fitted the stuff inside muy VII C, here I send you some pictures about.

[reddevil]

No, is a 650 CC normal one. It's an optical effect cause the deck is nearer to the camera and a little bit unfocussed. The ENGEL tank is the one fitted for my AKULA II.


And the second set of pictures is a mistake made when trying to load the desired ones.

custom job maybe, probably around 250 ml or less.

I reinforced mine with plastic beams below and had no structural problems with it. regarding air or water trapped under deck, there wasn't any problem at all with water when diving; you can see some tension with it when surfacing. And with air, the main problem is the bubble trapped under deck's rearmost part, where there aren't any slot.

Yeah. Been there, done that... The thing is styrene is a oil derivative as is petrolium jelly. Drop a piece of spur into a cup of petrol... Pretty soon no sprue. Though not as quick or radical the jelly will do something similar as it morphs with the styrene. As David said YUCK!!

ok. Wonder if sticking a small bar of soap below deck will help break up the tension?

[trout]

vital.spark, did you add any additional holes to vent air? If so where did you place them?

[vital.spark]

I actually sanded the underside of the VII deck smooth, removing everything but the overlaps then sprayed a smooth coat of 2K. My feeling was that if there was nothing there to catch and trap bubbles, so much the better.

The patrolium will leach into the paint as it works its way to the outside of the boat. What a god-awful mess! That don't work. Guess how I know!

[redboat219]

How about applying a surfactant to the underside of the deck to break up the water tension, like a detergent.

Or maybe even some petroleum jelly.

it seems fine now time will tell..i worry more about how it will vent water/air...

It will vent air ..... ONCE!

But, all subsequent dives attempts with a wet deck the air will not be able to escape the superstructure. Water surface tension will bridge those long, narrow slots with water and the deck won't vent through the slots when you flood the SD.

Therefore, you are compelled to open up big (no smaller than 1/8" diameter) holes in the deck to vent the hull adequately.

Water won't scale for you -- there's an apparent viscosity increase with reduction of model size. Hello, Doctor Reynolds!

I have spoken! So let it be written! (insert crack-of-thunder sound here).
