Thank you for your effort.
I used peel ply dont worry :) I meant with the glass... the vac leaves some extra resin spikes on the lam. I just put one in and wrapped it clear foil all around the board over the peel ply to pull it tighter before putting it in the bag. Lets see how this turns out. I actually didnt expect it would go as well as it did :) These are my first 2 vac trys of ever... Dig your work, those boards look awesome, maybe in a lot of years i will make to that kind of finish. Thank you for the inspiration :)
Im happy for my first try ever :) I will try to remember to post some pictures when its all done...
looks great. what's on the bottom?
Bamboo Veneer :)
By the way, i rolled the dice using some non amorim cork... Guess cork stuff with density around 200 kg/m3 works just fine, didnt have the time to order the proper stuff ;)
The engineered part is the space distance of the voids in the cork, along with thickness and density for a specific application.
So bottom from veneer to foam what is there? Did you wrap any fiberglass product sandwiched in there around the rails when vacuum bagging?
what is under the cork?
The bottom veneer was backed up with a layer of 4oz, then glued with the vac. After that i put another layer of 4 oz over everything. On top its 2x 6oz + 2mm Cork. Put it as a Hand Lam, gave it a slight shot of extra Resin on top afterwards, put on the cork and wrapped it with peel ply and some clear foil to keep the stuff in place. So on the rails theres a lap of 4 oz and double 6oz. The 2x6oz got a little bit wrinkled on the bottom by the vacuum...
Good to know, next time i will get the proper stuff :) In the meantime i found the distributor for my place.
Next time try bottom veneer with extra long lap overhang and vac bag with smooth peel ply wrap to deck side with extra long lap. Carefully sand veneer back to out line on bottom not cutting into lap to deck. Don't add extra 4 oz bottom yet. Put cork deck on. Pre cut cork deck with at least 1/4 inch over hand. Flip cork over and cut to matching size the fiberglass cloth, in your case 2 6oz layers. use your cork deck as wet out table for cloth and place on deck, pre cut peel ply. tape down, apply release film and bag as usual. when removing you will have an overlap of cork and cured fiberglass that you carefully sand back to shape. Place and patch preglass fin boxes, Tail and nose block if applicable. Bottom glass you board and do a cut lap on the deck side to allow for an exposed cork deck.. Final coat of epoxy on deck side tape off 1/2" inside your cut lap on deck and get epoxy resin to tape off. Pull when ready. Pinline before or after.
Pic of sanding back cork overlap on bottom. Just needs fin boxes, nose/tail block in wanted and a hand glass job on bottom as described above.
I will follow your advice next time for shure. Thank you a lot for sharing your knowledge :)
Heres a picture of the bottom, just got the hotcoat and heaps of dust :D Not the best workplace ever... Far from perfect, buts it is my fifth board, so i guess its ok. Always learning something :)
Hey charlie, ive been watching this thread with interest, Is there any chance you could clear up that last post? Ive been reading over and over trying to make sense of it but I am a bit confused. I'd really appreciate it if you could just break it down a bit more for us idiot novices. Love your cork boards, Thanks.
Basically you need to have the fiberglass cloth/carbon fiber, or whatever that is between the veneer and foam on the bottom, overlap past the rails a few inches towards deck. You do that with the bottom vacuum pull. Carefully take the bottom veneer or planks back to outline. Then you can more precisely take the cork deck to the bottom rail assuring a sealed board, that can be easily finished. For an exposed cork deck he would glass the bottom and wrap rails by hand. Then hard smooth rails and traction where it need to be.
Look at the lost boards and inspired boards that Drew Bagget manufactures. Same Idea but bottom is full carbon with a cork deck that does not wrap rails. Not exactly sure how he does it but boards are perfectly built.
Bottom line is if you aren't getting the cork on with the deck lamination by vacuum you are losing the whole point of the structural and performance advantages. Overlapping bottom and top fiberglass laminations between the bottom wood and exposed cork deck has to be thought out for quality and ease of build.
Don't have any old pics of of what I am trying to describe. Pic attached is essentially Litez's board set up. wood bottom and full deck cork wrap to rails. Hand glassed bottom . Deck glassed with colored resin and exposed cork area taped off and cut out. Final coat on deck with clear resin and I went inside the color deck lines on taped off exposed cork for a smoother transition.
Lots of ways to accomplish, you guys are smart and will figure it out.
