Thanks....

I was watching your lay up closely and noticed that you laid the top piece of 45/45 carbon weave on top of the glass with the bond breaker already spread, then placed it on top of the other two layers of twill carbon without flipping it over.... Are you not concerned with contamination?   

What are you using for a bond breaker on the glass? and what type of epoxy are you using for the carbon?

I've played with a lot of carbon over the years, and found that a thin kerf carbide tipped saw blade works excellent in a table saw for ripping those carbon sheets.   I use these for carbon and glass with a backer board.

Never got problem with this. I just use regular demolding wax, and clean every part of glass when it dry.
The best epoxy I found here in Brazil to do it is  Epoxy HEX 135 Slow (German Lloyd).
Tryed some others but didn`t work well. :knothead:

Looks nice this one! I will try to find some similar here.   :)

Wow! Brazil eh?   I hadn’t noticed your location. I don’t suppose Amazon delivers to Brazil…

That is quite a project building your own carbon backing and taking it clear to a finished bow…. I admire your dedication……Thanks for sharing this….   Kirk
