Thanks Starsky,
home building can be rewarding, but seriously the amount of times i wished i had not started it!!! money wise, the way i went about it, i could have bought a Top brand foil with board :lol:
you think im joking!!!!

good luck what ever you decide to do. Like i said if you want any info on how i joined my fins, let me know. i got pics and everything :D

Nice Job!

I am interested in your AOA comment. If i am correct the only AOA that matters is the relative AOA to the rear foil. In your experience what is the relationship that works well? Also, do you use a lifting rear foil? And what profiles did you decide on? Thanks for any info.

Hi guys,

Sorry for late reply, did not get notification of replys.
I'll post some pics later, not at pc at mo.
As for AoA, my forward swept wing I set at 0° and my rear is set at around -.5 °. The rear wing has a negative lift profile ie upside down wing. This set up worked perfectly straight out of the box, which I was happy with :D

As for the wingleted wing, like I said I was rushing to got it wet and did not check it's AoA. It was actually at a - 1° Which obviously no good. I managed to get it to rise but only to about 10" where it sat and any more angle it did not like it. But as I said I only noticed the aoa after the short session.

Thanks for your comment s, I'll pop some pics up of the fin joining process a bit later.

Cheers

Ok, so this is how i joined my kite race/ windsurf fins.

first i removed the inserts, then decided on the angle opposed to each other and weather to have them set at anhedral or dihedral.

cut the required angles and check all is good. i then had some carbon rod from inverted umbrella which i cut to make some dowels. i drilled into the tuttle head on both sides, i bonded them into one side when set i cleaned up and filled holes on other fin with resin then bonded and clamped with milled carbonizes resin. check fitment of dowels before using resin. in this one i even used a stainless bolt with a nut on the other end and placed it in where the insert holes were at the back of the wing. just check first where your holes will be!! just for a bit more security but this is optional.

once set, sand back as necasary and shape the foil profile on the underside. on the lower side in the middle i ground down below my final required shape. this was to take the carbon patch of ud cardon and a bit of kevlar. build up carbon running the ud across the join. build up higher so you can sand back to finished shape. i vacuumed this patch on both sides.

Sand back to required shape, drill holes, i used countersunk brass tube inserts in the holes. this was so the clamping forces was not direct on the carbon/ join etc. i have used the this wing without these but i put them in after. the forward swept wing i put them in straight away.

tidy it up, dash of paint, etc job done.
i made winglets from the tips i cut off of the fins. it worked really well using the dowels and is strong as.

they work really well and are strong. if you like them you can then make a mould from them so if you need to one day, you can replicate it.

Simple as that and pretty quick to do.

Hi, are the holes based on the alpine foil, if so do you know the correct positions of holes from centre line and space apart from hole to hole.

This is a pretty old thread.

Sadly, Edge19 can't respond.

Building a super cool foil is only one of the many cool things I hope he is remembered for.
