    Slieve, I'll certainly be doing the same for my carbon fibre spars in due course.
    David, very interesting read but could you change the colours used in the drawing. the yellow in partcular does not show up well.

    Gary,
    I won't be making a mast, just yard, battens and boom. My present mainmast will stay in place. It was used for a single sail before, and can do it again.
    But the braid is available in sizes up to 12 inches diameter, so in theory a mast is possible. Just a big project, like a big wooden mast, that sounds a bit daunting to me. I made a carbon mast, many years ago, using unidirectional tape. I didn't manage to get it any stiffer than an alloy mast would have been, but it was light and strong. It took an awful lot of work, laying up tape, and I'm hoping that the braid that's now available will be much easier to use.

    I was in the Mitre 10 Mega store this morning, and spotted some Norski products. Amongst them, some epoxy resin that seems to be suitable for carbon fibre, and of lower viscosity than West, more like Epiglass - but 60% of the price of Epiglass. It's a New Zealand company:
    I've taken a chance and bought 5 litres. I have no idea yet how much I'll need to make yard, battens and boom.

    The spar making sounds very interesting.  I have made several carbon fibre booms for various racing boats.  I used a foam insert from builders quality foam, wrapped the wet carbon layers around the foam added peelply and left to cure.  I removed the foam by dissovling with petrol.  Hey presto.... a hollow carbon boom.  To give them that shiney carbon look I applied polyester resin and 'faired' with this until silky smooth.  Worked a treat and I know at least two of the booms are still going strong......... ten years later.  Of course these were rectangular not round!!  But I see no reason why it wouldn't work for a spar.  The braided cloth sounds like a winner..........

    I look forward to reading about your progress.

    Hi David

    Please go the DIY way, BUT, please write it up step by step complete with materials, suppliers and costings. I think there would be a big readership for such information.

    Cheers, Slieve

    Paul,
    I'm well aware that there is a firm in North Shore, Auckland, who will make carbon fibre tubes to order - but have you checked out what they charge for doing that??? There would be little need to do it myself if I were a millionaire. 
    There is little need for you to be hand- making every single part of La Chica. Why don't you just go out and buy a boat? There are plenty for sale in NZ. If you like, I can tell you where to go :-)

    David,

    If you are going the carbon fibre route there's little need to manufacture your own. Carbon fibre tubes are readily available in just about any length, diameter and wall thickness that you are likely to need. If you want, I can tell you where to go.
