    The build log of my Sheerline Akula submarine

    Arrival of the box.
    Sheerline Akula Sdc10623

    Lots of packing keeping all inside safe.
    Sheerline Akula Sdc10624

    The two halves of the hull.
    Sheerline Akula Sdc10625

    Lots off little bags all nicely labeled as to what is in them.
    Sheerline Akula Sdc10626

    And of course the instructions.
    Sheerline Akula Sdc10627

    Bottom flood holes drilled out.
    Sheerline Akula Sdc10628

    Top flood slots cut out, not many on the Akula.
    Sheerline Akula Sdc10629

    Prop shaft support now in position.
    Sheerline Akula Sdc10630

    Sitting on its stand awaiting the drill, so as to drill the air release holes in the top of the hull.
    Sheerline Akula Sdc10713

    Front dive planes in position along with the WTC end stop in place.
    Sheerline Akula Sdc10714

    WTC rear end stop in position along with the prop support.
    Sheerline Akula Sdc10715

    Rudder and rear dive plane linkages in place along with loose lead ballast roughly in position.
    Sheerline Akula Sdc10716

    Rear lead ballast and center ballest loosely in position.
    Sheerline Akula Sdc10717
    Sheerline Akula Sdc10718

    Battery in position with front and rear end stops in place.
    Sheerline Akula Sdc10719

    WTC hold down velcro in place, the velcro replaces the brass strips and nut and bolts that used to come with this kit.
    Sheerline Akula Sdc10720

    This picture shows the top hull hold down bolt which sits over the prop shaft and is held in by resin.
    Sheerline Akula Sdc10721

    Tail pod and fin in position, the pod needs more holes in it than are shown here.
    Sheerline Akula Sdc10722

    Just another look at the pod and fin.
    Sheerline Akula Sdc10723

    Servo plate holding the water pump front dive plane push rod and the all important pinch valve and cam.
    Sheerline Akula Sdc10724

    Rear servo plate holding the drive motor, and also the rudder and rear dive plane push rods.

    A look at the conning tower(sail)and the periscopes made up from odds and ends from my bits box.
    Sheerline Akula Sdc10726


    After a bit of research on the great WWW, I found the correct position of the lights. Also found out that subs carry
    a flashing amber light for when they are on the surface, warning other ships that it is a surfaced sub with more under water than can be seen.
    Sheerline Akula Sdc10727


    The light system is two white leds, one on the front nose and the second on the rear pod with the
    usual red and green nav lights. The orange flashing light is in the wrong position but gives
    maximum visibility to surface targets, and is made from a small circuit board scrounged from a flashing display
    at a well known branch of chemist, all encased in resin and turned on by removing a small magnet from over two
    mocro reed switches on the front deck of the sub.

    Got the top and bottom catch done, it was not a simple job, in the end what I did was fix the bottom clip in place with resin, waited for it to set and then fitted the top clip to the bottom clip.

    I then ran a piece of insulation tape around both the clips. I then taped the top and bottom edges of the hull to catch any resin drips from the next step while the two clips were held together
    by the tape, I ran resin onto the edge of the top clip support plate then carefully lowered the top hull onto the bottom hull using tape on the outside to hold everything together.

    I hope that makes sense..when the resin is dry you need to borrow a long knife (carving) while her indoors ain't looking, slip the knife between the top and bottom hull joint and cut the insulation tape, you can then check the operation of the catch.

    Bottom clip.

    First bath test..this is fully submerged.
    Sheerline Akula Sdc10730

    Putting a bit of detail onto the deck, bits obtained from my bits box and the wifes sewing box (2X buttons).
    Sheerline Akula Sdc10731

    Went off to New Brighton on Sunday for her first run, I think she sits a bit low in the water at the
    moment, hopefuly this will be rectified soon.

    Very nice log.

    I think I read somewhere that subs are the only vessels to have flashing navigation lights.

    How long did it take to build her?

    Build took approx 2 1/2 months but still not quite finished as to the flashing orange light according to Wikki subs carry the same nav lights as ships and boats red green and white lights at the front and second white light at the highest point of the vessel with an orange strobe light in a prominent position so other vessels know that they are approching a submarine and the submarine could be longer than the approching vessel`s capt assumes or words to that effect
    I thought to put lights on it would be a good idea anyway just to be different

    glad you liked the log

    regards Mark

    2 1/2 months sounds very good and it looks very nice.

    I have never built a Sheerline sub but I must say I like their design and rugged construction.

    One way or another it has influenced my own sub models. (Copying could be the most sincere type of flattery!)

    Just a bit of an update on the running of the Akula...it's now been a while since I built this model. The sub was laid up over the winter, and on Sunday 18 March she was brought out of hibernation and given the once over. Once the batteries were fully charged, it was off to New Brighton with her...my plan was to sail the new Vanguard I have built, but due to radio problems this didn't happen, so here is a video of my Akula after a quick visual inspection and battery charge.


    Hope you like...

    Very nice video Mark, very professionally done (the wife, I take it?) The Akula runs nice, she's very stable, isn't she?

    Nice mate...very nice.
