Hand layup air bubbles are a problem, You can use a Heat gun to remove a majority of bubbles, use the heat gun over time, multiple times till the epoxy is set, like 11/2 to 2 hrs. Why were you even using peelply?I attempted peelply finish without vacuum on top of the board as mentioned on this thread, but got these bubbles. I ironed the peelply beforehand. What causes these? Possible to eliminate these without vacuum?
Did those bubbles develop as it cured? Then you have pinhole outgassing.direnc wrote: ↑Wed May 27, 2020 12:21 pm

I have at my disposal CF 11 oz. cloth. No stringers just foam core with cedar wood box for foil attachement. What do you recommend as far as Lay up with this particular carbon fabric? I will use vacuum bag most likely in 2 step process I guess?
Those bubbles developed as it cured. First two hours or so, there were no bubbles, and I went to bed. In the morning I was greeted with bubbles:(TomW wrote: ↑Thu May 28, 2020 9:03 pmDid those bubbles develop as it cured?

If they were there from beginning, you have not stretched out and squeegeed it down, or you have some contamination.

I want the deck to be completely flat so the tail is going to be pretty fat and nose will thinned out to get the front scoop/rocker. I have 11.8 OZ. which is about 350 gram/meter square carbon fabric in twill weave. I just want to use what I already have and that is why I am trying to work with this fabric and 20kg/meter cube foam and cedar lumber. Also I want the board to be "travel short" about 32 to 36 inch no longer than my mast which is 91 cm. Tom W what do you mean by "poited V" for box? Thanks again for all info!
