I´m trying to make a mould from a car wing that i have. I want it full carbon but i just don´t know how to make the mould to have a perfect join between the bottom part and the top part. Anyone knows a good tutorial on how to make split mould and how to bond the two parts with a perfect cosmetic finish later?
Thanks in advance
I found lots of good tips in this series to questions like this, specifically in Volume 2 & 3.
Sup Farbin, I was looking at those on Amazon the other day, will probably pick them up.
thanks! I bought the kindle version and it has some good tips but i didn´t find the answer for my problem.
Here are some photos to better illustrate
Make a top mould and a bottom mould, which key together.
Make a skin of carbon, trim flush with the mould edge (after cure) and after adding some more reinforcement if needed (some UD or so) fill with epoxyfoam, and close the mould.

but the epoxy foam will make it a solid piece and heavier no?
this part i have where is not solid. It only as some layers at the top so it can be attatched to the sides
Not sure if your part would have enough room to do this but this guy makes parts like wings in two parts with a flange and then bonds them together.
Most foams are reasonably light and having a core material will also add strength meaning you could use less carbon than if it were hollow. This saves money and weight too.
Of course a big or thick wing will get heavier but small wings it should be helpful.

the only way to make a wing without seams, is using a carbon sleeve, and inflate it from inside using a shaped bladder. needs a lot of experimentation in order to find the proper shape of the bladder, but once you do you re in the final strech. and nothing stops you from removing the bladder once it’s cured, and filling it with expanding foam for rigidity too. you can even remove it from the mould, inspect it for proper finish, and put it in again and pour the foam.
i don´t have a problem with seams. I just can´t figure a proper way to make them look good 
Yeah, very good for the basic non technical, non structural techniques for construction. If you are concerned with strengths, calculations, etc., this is not the series for you.
Also, Interesting seeing ya here.
Check this out. This may help. Wings constructed this way have been going over 400 mph in the dynamic soaring community.
