    Make Your Own Torpedo

    What do you do when you cannot find a torpedo to buy? You make one. This is 6 inches (150mm) in diameter and over 5 feet (1.5 meters in length). I have the contra rotating shafts and propellers worked out. I bought 4 inch diameter or 100mm brass model boat propellers with opposite pitch. I am still working out the issues on the gear box, electric motor, controls and batteries. I will also need to find a speed boat and design a launch tube. I will be conducting sealing and buoyancy tests in the local pool this week.

    Whatever sinks your boat. That tail section looks like its built like a brick phonebooth! You should chamfer the leading edge.

    That's for when you run into feral pigs swimming in your lake.

    SUPER IMPRESSED, with your fabrication skills in so many mediums and the initiative to start this cool project. Can't wait to see how it develops. Just awesome!

    I wish I also had your fabrication skills (and machinery!).........................
    Guess I will have to wait until a "real" one pops up

    Having stated that, I have over the years stumble across sites selling the real McCoys - In the UK there was /is a scrap metal yard which had a couple of Russian torpedoes for sale several years back. Another UK based organisation had a number of early Whitehead torpedo motors (4-cylinder /3-cylinder Brotherhoods) plus a number of MKVIIIs for sale.

    Also here downunder, one Mk VIII practice was sold when the Cowra War Museum closed about 2 years ago and got wind of another MkVIII in an interstate garage.

    They are around - however too big to hid under the bed "out of sight" from the OTMBO!!!!

    (I can sneak in and hid the fuzes ! LOL)

    I must note that this journey will not be inexpensive. I estimate that materials alone will run me $1000. Perhaps, in volume production, I might be able to sell them for $1000 each. I need to find rich yacht owners who want to equip their vessels with weaponry. Perhaps, the US or other Navies need high speed, inexpensive drones?

    It passed the sealing test. It did not take on a drop of water, and it has buoyancy to spare, but it is tail heavy. Now to design and build a gearbox. Then I will need a motor and batteries. Next up - speed trials.

    I will also add that I am the cool guy at the pool now - more of an enhanced stature than a change, really. Also, the ladies water aerobics group seems much more interested in me now that they know the size of my torpedo.

    Better to remain silent and be thought a fool than to speak out and remove all doubt.
