    πŸ“ Hull bottom skins

    View All
    Here the second of two halves clamped in place.
    The decks are supported bow and stern parallel to the bench to ensure no twist.
    The bow and stern of the skins are not glued yet but will be persuaded into place once the main areas have set.

    πŸ“ Weather forecast
    16 days ago by T33CNO ( Midshipman)
    Flag
    Many of my builds have been shelved, entirely due to the weather or the lack of degrees.
    If this forecasted warmer weather does manifest itself consistently I will have to shelve this build in favour of two others that are stalled for painting.
    First is my Stevns Arctic 75lb tug.
    I don’t have a blog for this here but you can see it in my Harbour along with a link to photo gallery.
    I think there is enough left to do to maybe start a blog β€œThe finishing straight” ?

    πŸ“ Resin coating

    I was up very early today so now already all the wood is sealed with dilute resin.
    This is a job best done outdoors as the vapours can have an adverse affect on the skin without good ventilation.

    πŸ“ Deck glued on

    Tomorrow I will be able to start sanding the frames. This is all important if you want your planks to fit with ease.
    I will spend as much time getting this perfect as I will fitting planks.
    I’ve still to acquire suitable wood stock, preferably obechi.

    Actually if it’s not raining I will resin coat all the inside surfaces first with diluted finishing resin.

    πŸ“ The aft deck continued ....

    As I prepare the deck to the point that I can make a template of it, I realise there is no support or provision for the mast and deck fittings πŸ€”
    So I’ve fitted a double deck with holes aligned below the deck skin to provide adequate vertical security

    πŸ“ Propulsion fitted
    17 days ago by T33CNO ( Midshipman)
    Flag
    View All
    Overlander 28/36 1120kv with maintenance free water proof propshaft and 35mm 4 blade type A propeller.
    The rudder is cut from 5mm ply and sanded to a taper
    I modified the keel and frame 3 to get the motor mount low enough.

    I've added a link to a video of same motor in my Hoga tug.
    I have an strong dislike of universal joints and their clakity clakiness so I make my own couplings that also act as an alignment tool.

    I missed the postman today but it was my propshaft and propeller from CMB that was fast
    So I’m now going to do the long aft deck next.

    Hi T I have used a building board for all my builds as that is the recommendation I received from the members in my club. Not sure I have heard of a scratch two half hull build. None of my scratch builds are are made in halves.Frame cut and mounted on the board keel attached and planking done while on the board. Your way must work just not tried it myself.

    Good explanation John πŸ‘ and sterling work 😎

    Personally I've not needed that method with a build so far, they have all been such that the frame construction has provided all the rigidity required. I find being able to move it around freely as I work much less awkward.

    Building boards generally, I feel, should be used on certain constructions of models. If we look at Companies such as Billings, the building techniques are generally well thought out and they rely on, shall we say, on the materials being used i.e. no warps or distortion in the plywood - to keep things true.

    If you look at this particular build, you will see that it is the actual deck and the keel of the model which is creating a stable building platform. The thing is, when you actually come to plank this model, you are relying on some way of holding it while you are planking it to prevent it slipping/moving all over the place.

    Billings, I believe, actually manufacture a jig for holding models, at a cost of course.

    The reason I particularly endorse using a building board is, it not only holds the model securely and gives you a good working area - as previously said it prevents any distortion.

    When I built HMS Warspite - years ago - it was at 1:96 scale, giving a length of something like 80 inches and I built this naively and without a building board / any forms of keeping it true. It twisted! I thought I would be able to pull the twists out when I added the anti torpedo blisters either side of the hull. Needless to say, it didn't work, the hull became a glorified plant pot - from then on I always use a building board - even when I built HMS Exeter at 1:96 scale and especially when I built the modern version of HMS York also at 1:96 scale.

    The other good reason for using a building board, is sometimes we build hulls, where the framework is rather flimsy, until we get the hull planking skin on. When I built the Seaforth, she has a large moonpool in the hull - this actually cuts through the keel of the model, so we need to support this area whilst building.

    Therefore, the building board use really depends on the type of model and also the construction method.

    I have added a couple of photographs showing the moonpool - you will see one is of the hull upside down and where I am opening up the hole for the moonpool, after planking.

    The other photograph shows the hatch open on top of the superstructure and this is the other open end of the moonpool so, literally, the moonpool goes right the way through the hull and even through the superstructure.

    Guess what, I like using a building board 😊

    No I cannot think of any good reason for that. None of the models in my harbour used anything so restrictive and non are anything but straight and true.
    As long as you plank alternately either side of the keel there is no need.
    I also don’t use nails unless it’s double planked.
    I thought a building board was only used where the two halves of a hull are made separately and then joined along the keel ?

    Hi T When you start planking will you be putting the frame on a building board.
