Hello Mat Great video, thanks again for that. After watching your videos, I also started building boards myself, so far a wingboard and a pumpboard. I like it a lot and have learned a lot, including everything I did wrong 😀. At night I'll also do a downwind board ;-) With the downwind foilboard you only have 1x 200g carbon and 1x 100g glass on it. Is it stable enough, no weak points? Thanks and greetings Daniel

@matshape 22 сағат бұрын

yes, that's enough overall, just the tracks and standing areas needs more reinforcement. Note that this is quite light, so it will ding more easily... but if you make boards, a quick repair from time to time is not very hard :)

You should slice a big chunk of a foam into layers (7-10cm), glue them well together so the layers go vertically, and with that you get a stronger board without delamination issues (and so won't be needed ugly vent holes)

@matshape 5 күн бұрын

I guess proceeding that way will act like a lot of stringers, but that's not really a concern with those thick boards. The vent is needed because i use EPS that has lots of void, so in the sun (especially for black boards) the pressure rises quite a lot inside. I'm not too concerned by the skin delaminated from the EPS as the resin penetrate in teh EPS, but the skin breaking chunks off within the board.

@sc0or 5 күн бұрын

@@matshape Exactly. With layering we reduce a volume which can expand, and so top and bottom coats move less and do not break ESP up (it can happen as inside ESP, as well us just below a surface like a delamination).

thanks! epoxy and polystyrene are local from UAE, quite expensive to ship internationally. Carbon, glass, HD foam from easy composite, and boxes from Aliexpress. Glass works fine too, and if it's your first board it's much easier than carbon to work with. Just make it a bit thicker to be sure. no need for a stringer if the board is thick enough, but you need the reinforcement linking the boxes to the deck. For straps, I'm not using any anymore, but especially for a prone board, I'd copy the placement on a existing board.

New one has a continuous loop all around, slightly convex on the inside, with double layer of tick foam in the middle, a back slightly longer to cover my sides better.

This is a really awesome video, so much good information in it. I watched it a month ago and just rewatched today. I started building surf boards four years ago and graduated to wing boards and downwind boards, all done with layups (no vacuum bagging). I'm getting acceptable results but I expect to really improve them using things I learned from you. The biggest change will be using release film as part of the layup. How do you calculate the required amount of epoxy resin? At one point you used 140 grams of epoxy for 100 grams of cloth and at another you used 150/100. I've been calculating epoxy requirements using Greenlight Surf's marine grade epoxy on the basis of 3 oz per foot of board length for a single layer of cloth, 4 oz for a double layer. Your method looks like it will be more accurate. I calculate my board volume the same way you do, by weighing the blank (foam only). It was nice to see that validated by someone who knows what they're doing.

@matshape Ай бұрын

thanks, I'm glad it helps. for resin Qty, greenlight formula won't work well for a wing board as the section is usually way bigger than a surf board. For me, I usually mix between roughly between 1.2 and 1.8 time the weight of fiber. The lowest would be for 2 layers with the resin applied on a flat table, highest for single layer with the resin applied with the fiber on the board and planning to have peel ply on top. When I add thick fiber for reinforcement, I tend to mix a bit more to make sure it's fully saturated and let peel ply remove the excess.

If i did it again, i'd keep the valve and closure system and just extend the other end of the bag.

@luxmonday Ай бұрын

Nice work! It will certainly be durable! I bet you could use a single layer of carbon and it would be strong enough... I took a minimalist approach for my pump board... I used a single 6oz fiberglass layer over white EPS foam with twin 10mm wide plywood stringers. It has held up, although I have had to fix lots of dings and it feels "soft" to the touch. Somewhere between your 3 layers of carbon and my single layer of fiberglass is probably the sweet spot!

@matshape Ай бұрын

thanks, that's the goal :) yes, less could probably work, but I wanted it as stiff as possible, and as it's a pretty small board, extra layers are not that heavy. I also hate fixing boxes... so those will most likely not go anywhere :)
