Looking great progress Carl :-))

If I am not mistaken, the designers of this Vessel chose the more conventional arrangement for the deployment of the stabilizer fins  O0 in that the pivot is FWD of the fin blade

Good news Carl. Upright with the mounting battens still on makes her look a bit like an aircraft carrier minus the flight deck!


 The details you have added should make her easy to build  :-))

That is correct Derek - the opposite to how they are on the Norland.

Great Hull Carl,
   Just wish I had room for one, still got the SD14, and three bath tubs to do, well that's what the wife calls them, Northsider, Wearsider, and Gragsider.
       Regards Howard.

I didn't realise the hull had such a sheer Carl. Very nice and crisp. Air bubble, bobble and chip free  :-)) Is the additional end detail taped on a cast or printed item? Looks to fit like a glove  :-)

Hi Ian
She has a very 'angular' sheer - it isnt a smooth flowing curve.  It's purpose was to bring the centre of gravity as low to the waterline as possible.  The main truck deck is at the level of the top of the hull belting and it was this feature that 'did' for her sister ship in that, once the water found itself onto this deck it flowed down to the lowest point and we all know what happened then.


The end detail you refer to is a 3D printed item and will supplied as such in the kit.  I admit, I was surprised at how closely it actually fitted the f/g hull but it will need a little tweaking here and there to fit better  :-)) .  There is a similar one for the stern too.  I felt that it would be better to add these as details as opposed to trying to mould them in with the hull.

It gives a straight edge to mark along at both ends as well.

Aye - that is true!  I have yet to trim the hull down to the proper 'top edge' yet so that bow fitting is sitting slightly higher than it should.

Been a little while since I posted an update here.  What with the full-time job, buying a house in France and then Christmas, time seems to have flown by!  Not been idle on the development front though - drawings to be created, parts to be tested (especially the framing for the superstructure!) and ideas to be gone through.


Have now progressed to marking up the hull and cutting the top edge to create the finished deck level.  This is quite critical in that it will dictate the finished levels and angles for the whole superstructure.  These photographs will all be included in the kit instructions as they graphically show the critical dimensions to be worked to:

After marking out the hull top edges, these were then cut down initially with a Dremel with drum sander attachment followed by careful sanding with a medium/coarse paper attached to a wide-ish flat piece of wood.  Doing this, it is essential that the hull is stable and level in both directions (hence the heavy batteries in the hull) and constant checking is done to ensure that both sides are sanded to the same level.  Once all the hull top edges have been reduced to the correct levels and angles, the inside edge is sanded back to give a smooth-ish (not too smooth otherwise the adhesive will not bond) and even finish.  Aim to achieve a hull edge thickness or between 1mm and 1 1/2mm - this will ensure a neat edge to the deck, not to say an easier life when actually fitting the deck!

Following all this, it was time to fit the wooden hull framing and deck supports.


I have found that it was easier to construct these frames off the ship.  The advantages of this are that a strong structure can be built ensuring that the parts are square and that, once fitted, it is easier to centralise the amount that the hull sides have to be pulled in - without distorting the hull or building in a twist.  These wooden frames are then glued into the hull using 24hour 2 pack epoxy - ensuring that they are 2mm below the top edge of the hull to allow for the thickness of the deck:

Cheers John  :-))   Getting there slowly %)


Got your message re Dortmund - just as soon as I hear back from the organisers I will be able to work out what is happening.  Should hear something very soon now!  Even Ron and the Peterborough club have not heard anything yet.
