This is been on the bench since about March... The idea was 'If the board is not all that important in the beginning.. why not the least expensive?' Also, why not use perhaps both the most used (and most derided) board ever. @ $175. (Amazon/delivered) it provides a low entry price compared to Starboard or the like. There are a surprising number of seemingly well-built foamies. Even Mick Fanning has a line that may get 'some' respect.
Like a lot of things, one tends to copy prior art. My young engineer friend milled up a foil mount suitable for the Brooklyn Bridge. Then you look at it and say; ' C'hit, just move the whole thing; there is no fixed position like with an insert?!' We have a stainless plate with four holes to add to the mix. ' Another banding device also because the junctions look like skin removal tools to me. When I get the time, I'll put up the shortboard. Be my guest if this simulates an idea, or 'you're welcome' if this saves you from a trip down a similar gopher hole.

...ooops! Pics to large for one page.

I'm assuming there is some glue between the plate and board? I don't think those zip ties are going to do much. Maybe tear through the board?

Ok, first, I love this. Now, questions.
What’s the top surface? Will it be padded?
I immediately have ideas on this based on the Gong HIPE. Bottom plate out of glass and carbon with maybe just anchors on top of the board under the skin. You can remove and reglue sections of a wavestorm skin pretty easily. That way the top is still mostly soft. If you routed out the eps and out in 1” thick high density blocks it’d be flush with top and smooth which is safer and still way stronger than anchoring in EPS.
It might seem like a lot of effort but in the end this would be a great way to get started more safely.
I need a new wavestorm soon, maybe I’ll use mine as a donor for a 5’ beginner prone foil foamie.
Love this man. Taking it one step beyond Sam P’s idea.

And this is the ultimate first boat session board even if it’s just duct taped on Piros style. Remember to shim.
-
Cool idea. Looking forward to a ride report.
My son's uncle dumpster dove a broken wavestorm, skinned it, dropped in tracks, reglassed, and had himself a 3 footer. I think a broken/old sup sounds like a platform to start with. A beefy 6 footer is way easier to foil than pretty much any 8 footer.
I am also concerned about the zip ties, entrapment as they loosen up can be a good way to loose a toe or finger. Maybe more through bolts around the stringer?

Clay you’re right about cutting down a WS SUP. Plenty of volume.
I’m serious about the duct tape or do a sub skin anchor like I’m talking about. I don’t think this sandwich plate is the final answer here. Bottom looks fine though.
But Clay's buddy’s idea inspires this thought. Cut bottom skin and strip out a 1’ x 3’ section. Route in some HD foam and set boxes. Then carbon and glass over it and build it up to match the skin level. I’m gonna say 6 x 6oz carbon at least. That would hold and wouldn’t require anything through the deck.
I think this might be my prototype.

Here's another that was done a couple years ago....

Was that one of those rivieras? Those have glass under the foam I think but not much. Like maybe 1 layer of 4 Oz. So not much stronger than a wavestorm probably.
-
Thanks, Cowboy... Ya, I have two rolls of EVA but ..'didn't want to waste either' if I cannot solve the banding. I thought about the pull-ties we used for concrete forms as a young fellow ...or the simple matter of making disk washers for thru-bolts.
Sano, the idea of making 'top deck - core block - bottom plate' all bolted together is interesting. I first wanted to try 'non-destructive' means, so it could be moved to different boards for different uses.
I have a mechanical tensioning device for zip-ties but it wants to crush rails. It would be easy to heat-form some pads as they use on large, cardboard shipping containers. But, you're digging in sand after a point. I have some stuff to ship in the next couple of days, but I will be back with a shortboard and different banding. Cheers.

I like it man. Non-destructive prototype. Keep em coming.
I need to start looking at craigslist for a donor.

Yes, it was a Rivi soft top, which did have the one layer of 4 oz under the deck.

Ah Roger that, and very cool idea wrt making it portable so to speak. Looking forward to the ride report.

Go for it wettie!
You are the master Rube Goldy, so you'll come up with something interesting :)
-
Checking back on this. Wetstuff, did you get this thing rolling? I’ve been rolling a design around and think I’m about to order some materials.
-
Thanks, Cowboy... I've been distracted. With 25ac growing exponentially + storm damage at home and a virus distraught wife, it's been hectic. I do have a 4-4 foamie in the corner and another, better idea. I hope to get back to it soon. I've been reading your progress - ' good for you!

Thanks man. I am a Zoner project lol. Any skills I get I have to credit to you all.
What’s the best guess on how far to locate the foil from tail? I’m assuming 18”-24”. Sound right?
-
Ok, so I’ve cut my plate out for the bottom of the wavestorm (foilstorm?) My T-nuts just came from Amazon. I’ve copied the position for the mount from the Gong Carter and adjusted for the extra 6” of length.
I chose to prototype it out of sande plywood and will layer three layers of 5mm with glass and resin for the test. I’ll duct tape it on, wax the top of the tape on the deck, and get Hdip to meet me and test pilot it. He doesn’t know this yet btw. Don’t tell him.
If it works, I’ll maybe make one out of divinycell and carbon, or just keep the weird plywood and glass one.
The plate is full bottom width so the tape has a straight pull from the deck for strength. It’s 32” long. If I make one out of foam I might cheat it a few more inches, put traction on the top and use it for dock starts and behind a boat when it’s not taped on and once I can surf a shorter foil board.
But this crazy idea is underway on my bench.

I went down this rabbit hole back when In 2018 when I was kitefoiling. I used this sushi board that wasn’t be used in my garage. I put and aluminum plate on the top and one on the bottom. Bolted my foil plate through both plates and board. I used it kite foiling but it was a little flexy for my taste. I may revisit this board as a prone foilboard. Will need to make a longer aluminum plate to help with the board flex. Carbon would be better but not in my budget. I have pics. But unable to resize them at the moment.
-
Classic GIF, Hdip. my wife asked, “what are you laughing at?”
The Gong HIPE inspired me. I figure with the board stringers and the glass/ply plate under my stance I should prevent most flex.
Long term we will see what to do. Not sure if I don’t just want to make a hybrid board if this works or stay with the weird plate on foamie. If the drag and weight don’t completely destroy the surfing of the board I might use the plastic fin anchors and 3m marine sealant to put it on. But this is a fun project either way. I’m trying to keep the soft top as soft as I can and avoid too much hardware.

I bought the carbon foil plate to do something similar. I've been working hard on the wiring for Fritz, my stupid Moho project, but with all the smoke in the air for the next few days working outside is probably kind of dumb. So maybe I'll jump on this and breathe resin fumes instead.
