Hi,

I am thinking of making a windsurf board, but I have a few questions that I am hoping someone might be able to help or provide guidance.

Most boards seem to be constructed as follows

1. EPS foam core
2. single / double layer of 6oz cloth ?
3. 5mm Airex/Divinycell layer
4. 2 layers of 4oz glass or carbon ?

Rather than having a painted board I would like to go for a clear or veneered board very much like this style of surboard below.

http://www.boardwise.com/p-5279-tiki-shortboard-slx-clear-surfboard-61.aspx

Just wonder whether this is possible and would the board be durable enough ?

Thanks


Justin

I got to ask why make things hard ?

Why not just go Clarke foam and polyester.

Add glass rovings eitherside of the stringer and down each rail on the underside.

Before all the people say it won't be strong enough, thats how all boards used to be and it was plenty strong enough.

Advantages are it is cheaper, qiucker and easier, and you know the first board you make will be bad, so wait until you make a good one in polyester before you go sandwich construction and spend the extra money and time.

Been thinking of doing it myself. Reckon I could knock out 3 in polyester in the same time and cost as one in sandwich.

Then again I would never pay money for a polyester board, so not sure how my logic works.

It can probably be done but it is extremely unlikely that you will come up with something anywhere near as good as what's available on the market, new or second hand.
The boards on the market now are the product of 30 years of design, trial and error over hundreds of different board styles.
To jag something on a one off design that is anywhere near as good would be close to a miracle.
But,... if you are doing it just for your own interest and amusement then go for it.

I would skip the 5mm and go for 3mm as its much easier to work with.. If you skip the paint its gunna be yellowing fibreglass over green Airex that will look like poo after awhile.. A good coat of white 2pak hides everything and keeps the water out..

The only reason why anybody shouldn't build a board is the spare time required..

Why learn to paint when you can buy $15 Picasso Screen prints? Why learn Guitar when you can learn the kazoo..

Now you have mentioned it, I will also explore that option as well. I assume that is basically how surf boards are made ?

I am only a light weight 70kg, so should be good enough for me.

Thanks

Have a look at www.ecboards.co.uk/ (menu on the left) and if you are still game after all that then go for it :-)

Yes there is indeed. Probably the most comprehensive board building guide on the web.
So you can ignore the red thumb from w^nker troll idiot

We went through a stage of making our own boards in the late 80's in Auckland.
We used polystyrene and put a 3mm ply stringer down the middle.
Then used 2-3 layers Epoxy/glass can't remember what weight. If I can give any advice it would be to take your time, don't rush, especially when shaping, glassing and setting the fin box & mast track.
Getting a good glass finish without experience is really hard and we ended up painting them with epoxy boat paint...Similar to modern boards I suppose. Get an electric plane.
It was a lot of fun.. especially test driving the one you made against your mates and comparing.
Also gave us something to do when there was no wind, in between changing the gear boxes in our cars to get us to the beach, but hey we were single with no kids back then.

I am working on mine since december (but I don't have much time and had to shape another blank since the 1st wasn't good)...I have to make stringer negative this weekend, then I'll laminate the bottom, after that I gotta work on the deck.

Shaping the bottom Vee was prety interesting and time consuming work, but I liked it.

I will put carbon fiber cloth on top and if it will look nice (no cosmetic failures) I will just put lacquer on top.

sideskirt I'm wondering what was so time consuming about shaping a v if you started with a flat bottom
be very careful about trying to get a clear finnish because you cant see the pinholes, when im laminateing i use a layer of 3oz satin weave, the weave is so tight it eliminates pinholes as well as makes things easyer when sanding the filler coat

Learning the Kazoo over the guitar is the easy way out, like buying a board instead of self learning the noble art of fabricating one yourself..

Here is a rare insight into what our music would be like if musicians always took the easy Kazoo route.




I'm also curious how shaping the vee was time consuming? was the blank cut with hotwire and templates like on ECBoards?


(Also second the pin holes- nothing is watertight unless its got a coat of 2pak..)

I'll second that!!! Board looks fantastic until you throw some solid colour at it, then all these pin holes pop up.

I've just finished a medium wind speed board, (53cm), and I fixed the problem on this one.
squeegeed a thin layer of resin thoroughly over it, after it came out of the vacuum bag.

Of topic, Hey keef, next project is a fin and custom footstraps for it, I'll get back to you when I've made some progress.

I found a load of YouTube videos uploaded by Nelson Factory (12 in all) which shows them building a board. The onlhy downside is that there is no sound as they have been recorded in real time and speeded up, but they are still really useful and shows the diffent stages of the process.

time consuming was learning the right way to shape....I had a very wrong idea...

laminating will be done by a boardbuilder who earns his living with this, so I am just shaping... I found out it comes about 70$ more expensive than doing it by myself, since I don't have any closed room where I could do it and no pump it is better way.
