    And the last piece...the motor box complete with 2:1 reduction gearbox.

    The module is now completed and will be here with me on Tuesday.

    My old mate Steve Pryce showing the module off before it goes into the box for transport down to me.

    Gentlemen, after a cock up by the courier company(they decided I'd moved from number 6 to number 8)my module has finally arrived, about twenty minutes or so back.

    It fits perfectly, couldn't be better...I am very pleased with it. Fingers and hands permitting, I can now get on with the building of the boat.

    The new MicroGyros auto leveller arrived this morning via OTW (Mike at MicroGyros has had to stop production of them temporarily, so any orders placed are being dispatched from OTW, who has a large stock of them at present)

    I'm shocked and amazed at how small it is...it's a quarter the size of it's predecessor, and weighs virtually nothing. How the hell do people see to assemble something this small?

    That's the next problem mate...I guess it's a case of stick it to a piece of double sided tape, shut your eyes, and hope it goes in the right place. The thing is no bigger than a Futaba plug!

    Richard to answer your question.
    Mostly people don't build these things now - it's machines.
    Have a look at:

    http://www.raspberrypi.org/archives/2675

    To have a look at the Raspberry Pi being built in Welsh Wales. (Interestingly not Chinese China!)

    Hopefully I'm recovered enough now after my last little episode to begin the last of the flood slots and make a start on the actual assembly of the Skipjack...I'm fed up seeing two large boxes of parts on my slipway. First job(after the slots are done)is to put the hull parts together and make it look like a submarine.

    Update as of 16/12/02.

    All flood slots now done, and I've just laid the parts together to see what's what. It begins to look like a Skipjack class sub now...I hope.

    Well, the module itself has to come back a fair bit yet, Andy...the motor box sits virtually right in the stern cone, so as long as there's room for the torpedoes up forward, all will well.

    Something like this, mate...the prop shaft needs trimming down a bit yet, but you get the idea.

    Working torpedoes...yes mate. Plans are afoot for six of them, all independently fired...nothing too potent though, just to look a bit good.

    Marius...that's part of the gearbox. Ron made me a 2:1 reduction gearbox for the main drive motor, the motor is in it's own little wtc and the gear run out in the flood area.

    The top picture shows the motor, without gearbox, in it's own water tight box...

    Moebius Skipjack - Page 5 70435510


    And this picture shows the gearbox fitted to the motor box.

    Moebius Skipjack - Page 5 70405510

    The long shaft you can see protruding from the right hand side is the propshaft itself, it runs in two bearing blocks to support itself.

    Hi Marius,

    Fingers and hands are not cooperating today, so I've found a couple of pictures that may help you visualise what's what.

    The end cap on the motor box is sealed at the end where the connections for the power come through, the watertight connections are nothing more than more than brass bolts drilled through to allow the power lines to pass through and sealed with aquarium sealant, this makes a 100% watertight seal.
