Did you make ribs out of the boards an glue them together again or did you use the boards as they were? Mine actually seperated in the woodcore itself under the binding. I could get you a picture of it as soon as get home to sweden again. But it sounds good that using it. Then maybe i could get the ...

I dont have a heated press and problably wont go for one either, Im only using a very low viscosity resins so heating it up wont help i guess. Unfortunatly all of my resin sources around europe have got the idea that epoxy needs to be shipped as dangerous goods. And that means the shipping rates gon...

Well, you pretty much make "pre preg" everytime you wet out a weave... Only difference is that you do not use extremly slow curing epoxy and put in a freezer. Im going to weigh pre cut weaves and then calculate how much epoxy thats suitable and roll it out wery carfully before i put it on ...

Hello Crismp Well that would be one way to do it. But i dont know how much weight you will save by adding a extra layer of glass first. Even if it is a very thin one. Do you think i will need one on the side below as well? Will the epoxy push up in the hole as well? PS: Im not really sure but i thin...

Now i have time to post some more coments. A nother bummer i did was to use whose fancy vacuum couplings. They made it inpossible to use the tire warmers i bought. The concave bases are because im using a to thin stel sheet to vacuum down aginst. So that would be switched out for the next pair. OAC:...

They say a picture says moore than a 1000 words, so heres more like 56000 words! In short. I have made the first ski with mixed results. The core was slightly miss aligned, wich with my thin sidwalls means that the wooden core there exposed in one place. Also the base wasnt the flattest but it may w...

There are several reasons for the assymetrical design. And yours is one of them. It al started out when i sat daown and started to think about what to do with a powder ski to make it perform better. And one idea was to use a diffrent rocker profile to the in/outside of the ski. To make it easier to ...

I have calculated on the pressure. As the press is for one ski i need about 15tons of pressure to reach 5bars at the ski. I think the jacks can be connected in seris by the oil refil plug but im not sure about if thats going to work. Still im holding on for vacuum, this is just an idea that im playi...
