    After my AKULA, which was a learning project, I start another scratch built.
    As material I now use modeling board or Polyurethane board, it’s a very dens foam, comes in various densities. David Merriman got me hooked on it. I will never go back to any other material.
    The raw materials



    Cutting the board up



    The cutting resulted in a pile of blocks with were carefully labeled with purpose and dimensions. This stuff is expensive so you don’t want to end up with a huge pile of waste, so think before you cut and measure twice.

    She is now resting in the "ready to paint and finish" box.
    missing but not forgotten, bushing for rudder, towed array exit hole, hatches

    Stern master

    Post  bwi on Mon May 07, 2018 9:57 pm

    Test fitting all the parts for the stern. No real issues found.

    Now the most time-consuming part to be dealt with, the alinement of the planes and rudders.
    Lessons learned from my AKULA, don't forget to give enough clearance to compensate for the primer that will be applied later and for the final paint coat applied when she will be finished.

    stern moulds

    Post  bwi on Mon May 07, 2018 10:13 pm

    Maybe a little bit to early to post this.......maybe it will not be exactly clear to everyone what I'm trying to achieve here.....It will become clear in time when I start the casting.

    My intention is to make the moulds by shaping some modeling board and use a thin jacked of silicone to take the shape of the stern master.
    The below picture show the support moulds in with the silicone will sit. I had plenty challenges here, I wanted to integrate index lips, cast the stern hollow by means of a caliber,......

    If it will work I don't know but at least I had fun designing it.

    All this resulted in two Articulated moulds.

    Dowel pins and pockets (clearance between them is 0.02 mm) I think I made close to 50 pc of them know....and counting



    Caliber mould, with integrated dummy index lips





    the articulated master mould assembly



    All parts of the moulds
