    I guess I already have posted some drawings of my fantasy boat project, which is loosely based on a 209 type. This is a project that I'm slowly starting right now. After the extremely complex U-1 and the still very complex Nautilus build, the modelers heart longs for something much more simple. This is going to be it...a small boat with WTC, single screw, no milled parts (with exception of the hull masters).  

    It's going to look somewhat like that:

    New project - Neptune Neptune_zpsogorieva

    New project - Neptune Neptune-2_zpslabgbcho


    I'll kick off with the WTC. All very simple. The structure parts were 3d printed. I'll make silicon moulds based on them and then cast PU parts. The dice system will use a peristaltic pump and an inflatable rubber tank.

    This si the design::

    New project - Neptune WTC_zpsebnrqajw

    And the first 3d parts arrived today....they are green because I ordered them on St.Patrick's day and green plastic was cheaper that day ;-)

    Bajonet catch fits tight:

    And here we go: To make reproduction easy I want to cast the structure parts using PU resin. Therfore I have to make silicon moulds from the masters. Glue the masters to a flat board, frame.....

    New project - Neptune IMGP0494_zpsmnynqdvi

    Cover everything in 2K silicon.....

    New project - Neptune IMGP0497_zpsdtazh6yp

    and we have a mould.

    New project - Neptune IMGP0498_zps5ww8ddw4

    And the first cast parts.

    New project - Neptune IMGP0499_zpscenqefbf

    Couldn't be easier.

    Moulds for the front and back bulkheads are next.

    As promised, the silicon moulds for the front and aft bulkhead are done, and the first parts are cast:

    The bajonet catch fits tightly:

    New project - Neptune IMGP0507_zpsez1c5x4x

    The counterpart is already glued into the WTC tube:

    And complete:

    Next is the inner structure...

    Well, a quick snap together of the inner structure:

    New project - Neptune IMGP0510_zpsyunoffwl

    The end plate of the peristaltic pump has been trimmed to fit the PU cast supports:

    New project - Neptune IMGP0512_zpsgrme7bf1

    Everything is held together by two 4mm diameter GRP rods and a 5 mm diameter brass tube, which also serves as water intake for the pump:

    New project - Neptune IMGP0513_zpsodjsqlk3

    Well, basic inner structure done in about 1 hour - had worse deals than that:

    During the week I glued together the part of the inner strcuture. The pump is screwed to the support frames. Behind it sits the pump controller on a 2 mm thick GRP board. The free space will hold the rubber sack for the water. Then the LiPos and behind them the two servos for the aft planes.

    Slowly everything falls into place. The dive controller is screwed in place and I started wiring the whole thing:

    New project - Neptune IMGP0517_zps6kwmgavt

    The hoses are hooked up. The overpressure switch is new, not the one I got with the controller, as latter was too big. The new one fits tightly into place below the dive controller. The hose to the pressure switch starts in a T nipple and is routed over the pump motor to ensure that no water reaches the switch. And it looks cool....

    New project - Neptune IMGP0518_zps6jwcphuj

    The battery rest on two 2 mm thick GRP planks:

    New project - Neptune IMGP0520_zpsoiigz9ni

    This way the battery can easily be fixed with cable ties:

    New project - Neptune IMGP0521_zpsb2hef4ot

    The gap between battery the GRP deck has the advantage, that in case anything gets wet, the battery can easily dry. And the gap is well suited to route cable ties to fix additional gear:

    New project - Neptune IMGP0522_zpsjuw3u3f5

    e.g. the receiver. It will simply sit on top of the battery:
