Diy sup foil

[supuk]

Managed to finish the new sup yesterday and got a quick session on it this morning, want to play with a few of the foil setting just to dial it in but for a first surf I was supper stoked, so much more nimble even compared to my 7'4 you do however loose a little glide however I do have a design in the pipeline that will be along the same principals but a little more down wind specific.

I love the selfie Charlie! Lots of joy on your face with the new board.
Thanks for the hot wire tips.

cheers im pretty hard on myself and if a board doesn't feel good it bugs the hell out of me so I have to build another almost straight away so when make a big leap and get on a board that instantly feels right the stoke is strong! that said im never really satisfied there are already a few micro changes I want to try but I can probably do that without needing to build a hole new board this time

here is clip from the boards first wave, like I say it was tiny and its a trick wave to foil as its a super narrow wave in a river mouth and the sand bars and currents do all sorts of crazy things to it but I normally have it all to myself in the area that's best for the foil.

I went after the wings with the modified templates.
It is all as Charlie said, four hands would have been easier.
Some spackle and sanding will be required.
I might consider some 'softer' wing tips after reading Pono's latest thread asking for safer designs.
Hope people are OK with my decentralized posts, just trying to acknowledge where I am getting ideas and stoke the choir...

Nice wirejob. Are you aiming for a clark-Y type foil?

[jrandy]

Thanks Bill. I was shooting for a 4412 with 2.1sqft (1950 sqcm) area to boost 300 pounds at 5.3mph.

That’s not bad for a first go I normally mess up a few before I get a nice one if I have not done them in a while. That’s the classic one side finishing before the other on the leading edge, try cutting the other way perhaps and Finnish at the TE, but like you say you can easily make those work as you want a rounded leading edge anyway

Jrandy, I like you popping in here and there. It's like a scavenger hunt.

Wanna see this all come together. There are so many good builds going on here.

Been busy working on the new prone board as we have had a anouther spell of very cold weather with very few waves. Hoping to get the probe board finished this week and with the excuse of using up offcuts of foam I have cut a new dw foilboard over the weekend

Grabbed this interesting picture of facebook of a gofoil maliko 160 which clearly shows the construction and the airfoil profile. defiantly not the 100% carbon foil the claim it to be.

two other pics

Interesting, so 100% means 100% of the fabric is carbon but not solid carbon. Explains the floatation.

I don't see a problem with this actually. The leading and trailing edges are solid. Makes me feel better about my construction now too.

Wonder what the mast looks like.

[supuk]

yes I would not have expected it to 100% solid carbon except maybe the mast, I was expecting perhaps the wing to be hollow but 100% carbon, like you say I have no doubt all the cloth is 100% carbon but the foil as a entirety does not look like it. I expect the mast is the same, I think beasho said he has seen a broken one.

Is that two kinds of foam in the middle?  Can you guys guess what they are?

[supuk]

My guess would be a high density core like airex and the expanding epoxy around it, it doesn’t appear to be a very close tolerance core though. Not sure what the Black leading and trailingedge are could be carbon or just adhesive.
