Thanks Plummet. Definitely. It is a work of art to get them exactly the same. Considering I shaped it with only a grinder it's not bad at all!
Now just for the tricky part. Attaching the mast....
The Indestructo foil is the first picture on page 1. I made it because the other guy testing my foils has a special skill for breaking them, even after they have lasted me 2-3 sessions, he has managed to break them without evn hitting the bottom, or getting on them, after a single using a power stroke and doing who knows what with the board shape.direction. Probably trying to ride it sideways.....
Well.... If you want performance, the trailing can't be a "fat" edge, so it's got to be somewhat sharp, leading edge not so much as it's bluntish. I saw a research paper on it, and the sharp edge performed better, the gains were not worth creating a sharp front edged foil however
There's a thread on it . . . elsewhere. I wasn't that interested in it as I don't care about ultimate performanpace or going fast I remember seeing this page: claesjohnson.blogspot.com/2012/08/rounded-or-sharp-trailing-edge.html
Hey Guys - if you are in Sydney and could come on down to the NKL Series II at Dolls Point next year 20-21 Jan - we would love to see all ya foils and give us all an exhibition foil display at 11am before our comp starts. We are introducing a Foil Race in 2018 and have our 1st event in 2017 at RBYC Melbourne for 1st timer foil racers. Love all of this thread - very innovative and exciting. Lets see whose homemade foil goes the best - Not Official NKL so no fees etc - but just an exhibition by addicts for fun. Georges sailing club will have a few of their guys out too. www.nklseries.com
All of your foils are a bit more professional looking than mine. Mine looks like the sub $10 foil that it is . Well if it works I will be super stoked. To be foiling for less than $10 is an achievement. It doesn't even need to be fast or high performance. If it is rideable and can go upwind I will consider it mission accomplished.
Final layers of carbon going on tonight. Going to be fun unwrapping my new foil tomorrow !
Dialled in wingtip washout and tail stab angle of incidence too
Finished, clear coat drying..... I hate clear coats, but needed to trial one just to be sure they are crap.
Chopper very nice work! I have been following this thread with interest. Great to see people making things, my background is manufacturing.
I have been developing a foil for the last year that is almost ready to bring to market. Its almost home made with all prototyping done in my factory.
Some parts have 2 layer carbon, some parts have 5, it's all about stiffness, but carbon is only as useful as the compressability of the stuff in the middle, and the tightness of how u wrap it. My indestructo foil was 2/3 layers and I can now say much easier to ride than a certain unnamed production foil that I tested. .... and regarding laminating, wood as a mandrel, .... is much softer than plastic unfortunately.
( unless u using jarrah) ...maybe
