  • Yeah i know, me like complexity, frankly said, i have no idea how they kept their torps inside the tubes, there was no room to use those lockingballs as used on your gastorps, so i ended up with the hook thingy, on the dry it works well.
    This week i'll do some testing with launching from the tubes and give the mechanism a rub down to iron out the defects.

      I love watching the Master at work (don't tell anyone I just said that!).

      • As for the Master thing, i screwed up my torps, that is, props only, the rest is fine.

        During a few tests the propblades started to bend towards the torpedo-body, you would expect the other way, the other prop simply shattered, i must remark, all blades are silver soldered for strenght, what the hell is going on!!!

        I still want to do some tests this weekend, so i ended up with a slight modification, three blades nylon props, also a bit smaller diameter.

        I coocked my brains about the propellor issue, my theory is that starting up those high torque torps sends a pressure wave agains the closed back of my tubes, this would explain the prop blades being bent towards the torpedo-body, the light went on when i was thinking about the tubes of my type XXIII, same method of launching but no shattered blades, the picture shows my solution, drilled as many holes i could into the backplate of my tubes.
        Now the pressure wave has a way to get away instead of deflecting, pretty much the same arrangement as on my type XXIII, tomorrow i'll shoot some vids about launching the torps, stay tuned.

          After this test i decided to molest the tubes even more,

          To solve the issue of pressure even more, i decided to drill some holes into the sides of the tubes.

          As you can see i now have some inlets to get me a better free waterflow when starting up the torps.

          For now i'll dig up the jigg for reparing the old brass props and do some more testing with those props to see if my modifications work.
