Looking good John any ideas on a colour scheme?

[john_hamilton]

regarding colour, i have'nt got the foggiest apart from its got to be individual

Going for a box case. Is this because you haven't built the board yet or you want to play with different shapes?

[phil_kirk]

As i understand, both Daryll,
We used the same case concept and leant John the mould to save time and effort.

The box also allows for the unnexpected grounding damage without damage to the hull integrity and a complicated intrusive repair.

Looks like they can't wait to start playing with it either, spotted on Digby's Facebook!

THE SUN! I remember that. Leeds is so very...gray.

Any progress with the build?

[john_hamilton]

right, i have not been home for a month recently, so very little progress, and also no access to the forum
i have a question though: when im trying to fit my deck, i need to make holes for the rear rack beam supports, how best should i do this? i was going to use a dremel and cut upwards whilst the deck is on so i can get the holes in exactly the right place.

also, when finishing the fillets off with carbon, how much of an overlap is needed?

[phil_kirk]

Ok John,

You can use strips of carbon weave about 7cm wide.   This should give about 25-30mm overlap either side of the fillet.  Cut strips a little wider because they will fray when handled.  I think we used about 10cm wide strips which were excesive in hindsight.

you should fit the rack supports first carbon them on to the hull.  then place the deck over the mast stump and lower down on to the rack supports and jib track ends.

Then draw round the rack supports on the underside of the deck.  Remove the deck and cut along the lines.  The aft racks should sit above the deck level.  I fited my aft racks first.

If you have a weekend or even a Friday/saturday I could come up and give you a hand.

10mm overlap to fibres is Ok if you are really neat.

Cut the strips on the bias ( ie at ±45° )
Then they don't fray at the edges
easier to stay bent around corners
twice as many fibres  across the joints.

Plain weave is stiffer and better than twill which wobbles about and gets a mess / stretchy .

Also do it this way for gunwale joining etc.

[phil_kirk]

Andy's post makes good sense and I am grateful that he has shared this with us.
My experience with using +-45 degree strips was that I found this tricky.  To avoid the strips getting narrower and longer you can wet them out on a strip of polythene and transfer the wetted out carbon to the joint on the polyethene.  otherwise wet out in situe on the fillet. I find that this gives the carbon a choice of sticking to the brush/spreader or the boat.

If you can perfect this technique and handling thin strips of weave/twill weave you can save some weight and money.

Good luck!

In regards to colour, how about this for inspiration!
