I'm building a slalom board with a low densiy eps core. Does anyone have any suggestions on what to use on the deck that will wrap around the rails nicely. I want to keep the board as light as possible so core mat is not an option. Ive only ever used divincell on the bottoms of previos boards, never had any success trying to get it around the rails. I also have enough carbon left over to layer one side of the board. Does anyone have any ideas on which side to use it???

If you can lay your hands on some airex, it doesn't require heat prebending. But the last lot I got came from NZ. It's also a bit softer for the same density, so it dents easier, but is much tougher and won't fracture any where as easily.

It's possible corecell is similar, think that's available in Perth now.
Something to do with if it's "linear linked" or not.

Smithers are you migrating to WA or just want people to think thats where u r from

Airex is similar to corecell, quite soft and bendy, very easy to use.
2 x 200gms on foam would need a high density blank , I wouldn't do it.
I'd go 3mm H80 divinycell as Juice mentioned, Huntsman are the distributors and if you want light go pre-preg.

use contured divinacell thats what they make it for its on a fiberglass backing

nice job mr

yes only use brown balloons fill and sand after cureing,you dont need to vacbag cos cells are filled with balloons,you mite save a few grams with a vac but if your not set up for vacing,just get a bleeder and wrap with glad wrap

I guy I know uses a frame with a whole pile of elastic straps, reckons he hasn't had any problems, but I prefer a vac bag any day.

Yeah but how do you get enough even pressure all the way round. I just think it would be risky building a sandwich construction board with no vac. But if you've done it fair game to you.

Fair enough then.

THe fridge compressor as a pump article is on the links for "windsurfing articles", just to the right of the forum threads. A good article.

G'day fellow builders, thanks for the smiley faces.
Smithers, it takes about 30 mins to do the bending with 5mm. 3mm would be plenty for a slalom board or wave and a lot easier to form.
I do use the proper gold bagging tube as used below, it's not cheap ($13 per mtr) but have bagged 12 sides with just one bag and could do another 12, worth it in the long run.
Breather, when bagging 'd' cell almost anything goes. Shade cloth is is best but I have used coremat, doona wadding, chopped strand matt and even the curtains.
Once it's in the bag as here it goes on the rocker bed with phone books on it so she dosen't twist or end up with more rocker.
Happy bagging
