Diy sup foil

[Newps]

Very cool looking new front wing.  Your ability to churn out new designs is inspiring.  Thank you for sharing.

I like it too.

Was this shaped flat and then cut and reassembled, or did you shape it with the anhedral?

I'm gonna try to start mine this week. Turns out my charger is only 1 amp. Won't get far on that so I'm searching.

Yes I shaped the two half with a straight leading edge and got them symmetrical then added the shape to the tip, then glued the two halfs together in the center for with some of the anhedral and then cut the tips to add the poly anhedral.

Got a fare bit done over the weekend booth sides now bagged on the front wing and now all sanded and the tail has gone in with both sides all in one go.

[surfcowboy]

Can't wait to see how this one flies. Could be a game changer if a simpler shape performs well.

 Out the bag and cleaned up and ready for a hot coat.

Holy Mooochoooo!

Are you looking for some test pilots? 

I love the Go Foil but your artwork is looking pretty fantastic. 

Truth be told several of us have our foils in "The Shop" I am suffering from the "One is None and Two is One" mantra. 

I am looking for a backup option when things need a repair.  Sadly this applies to:

• The Foil
• The Mast
• The Board
• The Surfer

Cheers one I get it how I want I’m happy for anyone to try it’s just getting that feeling right like any board till then I’m happy to test them myself

How are you all breaking them? What’s failing or is it just running into stuf?

One Mast delamination (like a piece of carbon stripped off the mast), One subtle crack at the Mast to Tuttle connection and One catastrophic mast to Tuttle connection failure.  Different brands.

All of these were under "normal" use scenarios.  NOT from a single defined impact event.

interesting, doesn't  sound great! its fine when traveling in a straight line but there must be huge forces on the masts when loaded in the wrong directions from getting tumbled in the surf so it doesn't surprise me.

its taken a year of learning CAD i have made a big personal break through today.  I was going down a dead end road which were never going to allow cad to do what I wanted properly until some one noticed the problem in the method and the result was frustratingly simple! anyways now I have figured It out it finally opens the the door to experiment a lot more accurately with wings as soon. Just got to figure the best method to create quick cheap mounds for one off's but I have a few ideas floating around upstairs so we will see. first I want to test the freestyled 

[surfcowboy]

Dude! That is insane! I know how many hours you put into that but I suspected there was a fix since the Chinese foils were hitting. Congrats. Now get to work!!

I've looked at a Chinese SUP foil now, and for this one anyway, I doubt it will really work. Several reasons, but the most telling one is that the front foil profile looks like nonsense. Without cutting it in half I can't be sure, but I think it's just a symmetrical foil with camber. I can't see how it could generate significant lift below 10mph with some positive AOA. Are there kite foils like that? Could be they just made a kite foil wide and thick.

I spent some time at Dave Daum's shop last week during my SoCal trip. He's got one hell of a shaping system. Huge. He has interesting takes on how to build wings and keep them from flexing asymmetrically when bagging. The guy is a master of his shaping machine.

[supuk]

I think I know the Chinese one you mean, no I have never seen a kite foil like it and like you say it won’t work at the speeds that are useful to us and be controllable for many reasons. I know at least one company trying to flog these for near the same price as the bigger brands, it’s quite comical!

I have seen a little of what Dave does from his Facebook posts and videos, his cnc is indeed nice. What’s he doing to stop twist? It’s not something I have incointeredproblems with yet but a lot depends on the shape of the wing.

[PonoBill]

His bagging setup is pretty complex and hard to describe. But one thing I thought was interesting is that he shapes one side of the wing and then glasses it in the block. Then flips it over and CNC's the other side. Gets a stable base for the second cut
