    Oh fantastic. I'm not the only guy making a ton of rudder test articles.

    Getting there. Testing weight, about 4 lbs under, looks like I'll be able to fit the 2nd bottle

    was nice to make a wooden mount for a change, didn't have the room for a plastic one of sufficient strength

    Yes, I want to see how many Gearings I can shoot through ;). It's something a few of the juggernauts of the hobby have mentioned to me in the past. One goal for the build was to give myself enough room / displacement margin to fit a second bottle, and it looks like it'll work out with the bow area being empty. We'll see, I'll probably hook it up and test it out at some point.

    Are your two bottles on the same air system? Tim tried that in Vanguard and it didn’t work. I think the regulators “fought” each other. He was trying to keep more air for the duel sidemounts. He changed the system to have one bottle for each side of the double sidemount. Basically 3 of the 6 guns one a bottle.

    You'd have been better off using that scheme in the Mo. It's kind of wasted in a Scharny.

    I have a few configurations I'm going to test. Getting the regulators to play nicely is the main concern as it would be on any gas system. I'll try the direct connection, if that doesn't work then add one or two check valves (first on lower P reg), and if that doesn't work then just do the 2nd bottle to the third triple (maybe pulling other check valves from system), and if no benefit then retire the idea from this build. Of all of the experimental stuff on this boat the two bottle setup will require the least amount of work. It's a good idea for Missouri but that would require a full refit of the innards to get the geometry needed. Also probably a good idea for the KGV in the future.

    Doesn't matter
    for 2 tanks, would something like a shuttle valve fix that issue? like a Clippard MSV-1? The Bismarck I have is set up to run 2 tanks, my plan when i got to it was to just use one of those valves. I would imagine that the size and/or weight for the performance needed out of the valve might be a hindrance but I don't have much knowledge in that aspect of ships.

    6 bow gun Yammer had 3 independent regs/bottles . Each system supplied 2 guns

    I've seen several attempts to use multiple bottles in Big Gun ships. In each case, it proved impossible to connect two bottles/regs to a single air system. It was possible to run two bottles to a single regulator using an ASA, but the most successful systems just used two independent air systems.

    What in the Hot Crispy Eleven-Herbs-and-Spices Kentucky-Fried Chicken did I just read.

    Who did this?

    This is a story that needs telling.

    I remember seeing one at nats in oakboro years ago. It was used in the convoy battle and was awesome to watch it shred convoy ships to pieces.

    In less interesting news, I got the triples wired yesterday. Made up a test switch mount

    That is Andy’s CV. Not sure who was driving it and thought it’s a good idea to stop in front of all those guns. Some people can’t drive.

    Sounded like Stalnaker

    Finished main wiring harness. At the stage of the build where it's becoming more of a 'make-it-work' mentality. Still optimistic about Georgia, will bring for sea trials if I don't get it on the water beforehand

    Definitely a full house mid-ships, I think I'll go up to 20V on the outboards and move that ESC to the bow, so I can slip the pump ESC to STBD side. Making up a new box with a 4th servo lead coming out. Main thing left for internals is running hoses, then a few small things here and there.

    Rats nest will be cleaned up once functionality is verified. Getting batteries in and out will not be the cleanest job
