Few questions about board building

[lamza]

Hi all of you, I am building my first kiteboard with fiberglass, epoxy and samba wood core...
I want to ask a few questions, so please answer if U know....

1. Which pressure has to bee when I vacum baging the board?

2. Which material is best for puting graphics into the board, between the fiberglas? cotton, silk or something third?

3. Which is the better way of vacum baging? To put board into the nylon bag, then put to the rocker, and to put some weight to make rocker on the board, or to put it directly to the rocker table and to make rocker on the board with vacum?

4.is anybody using gelcoat for the topsheet?


Thats it..

Thanx,

Sorry for bad english :(:(

you've covered a lot of ground with your questions.

perhaps reading a few of the vendor tutorials will help give you a good build plan.

also yahoo groups boardbuilding has the most variety of build techniuqes.


relatively heavy wood cores typically do not justify vacuum bagging as a means to enhance good stregth/ weight properties.
but its still a good clamping method.
wood cores can handle a lot of pressure so if you bag it use as much vacuum as you want.

good,fast, cheap .....pick any two

How mutch vacuum depends on your layup method. If you are using some sort of peel ply + breather and your resin has a lower viscocity, too much vacuum might dry out your laminate. Do some tests before attempting it on a full size board.

graphics??? who needs them??? they don´t make the board perform any better! I never bother about them, they are useless unless you are buying into the marketing bullshit.

How to bag depends on your core and how you laminate. it you have concaves or chaels shaped intoyout core, you have to use a ful bag. If you are building a flat bottom board or are transferring concave to your board using an insert in your vacuum table, it is best to clamp acainst the table.

Gelcoats are more usefull in molded parts, not very pracical for kiteboards.

My suggestion: KEEP IT SIMPLE!

both materials shoule work fine for graphics just silk will weigh less
