Sorry for the delay,

Can you step through the finish technique you used to get that perfect clear gloss surface? I see you strip off a sort of peel (what is that stuff?)

I use 0,25 mm thickness PET sheet, usally it has a good finish (put some demoulding wax after using it).

How did you like the double wing foil compared to a single?

the double wing is less sensitive to the turbulence and the foil need less speed to start working, it as also a good stability.

Now the new foils are finised and tested.

I add some pics and, as soon as I can, the new two videos (constructions and trials)

Cool stuff, looks like lots of work!

Interesting with the infusion process, are you infusing the laminate under a mylar or vinyl sheet? Is that what is happening? love to know more??

Cool stuff

Thanks, for me is a great honor to receive a compliment from who is without doubt the leader in the foil field.

are you infusing the laminate under a mylar or vinyl sheet?

No, I don’t think it is possible.

Is that what is happening? love to know more??

Sorry, but You are thalking about the board or the wing?

Those things are works of art!

I think he’s talking about the bottom skin infusion as you show pulling the sheet of mylar off after it is bonded to the board with a very nice finish.

Do you have any idea of the resin content of your infused skins? I’m looking at doing a project with infused single ply skins and I’m wondering how easy it is to get a skin with a good resin to fiber ratio.

I mean the board when you peel off the PET? is the laminate under this infused or done some other way?

I love the contrast between wood and carbon fiber, so, in order to obtain my logo on the board I had to proceed in that way:
infusion of single layer of “custom” spread tow and cure.
cutting images with knife
epoxy on the bottom board (wood) + layer of cutted carbon +epoxy + PET
the whole in a vacuum bag.
At this point starts a boring and manual operation. You must uniform the amount of resin and push from the center to the corner every air bubble.
I knew that from an industrial point of view is a stupid method but, in my case, for a single and unique board with this kind of decorations, i think that there is no way to use other process.
A single layer of spread tow for sure isn’t processable by infusion without mesh and peel ply in one side.

I’m looking at doing a project with infused single ply skins and I’m wondering how easy it is to get a skin with a good resin to fiber ratio.

With the infusion process there is no problem about the quantity of resin. You always reach the right amount (if everything is well done)
