Hello everyone

I would like to present my first board.
Lot of work, lot of money...
so, board is 135*41, rocker 2.5cm, concave 4mm
core western red cedar 8mm thickness
rails epoxy
fiberglass 600g triaxial ( I'm not really happy cause not transparent)
the board made like snowboard technology, 4bar pressure and 75c temperature
the board pretty lite 2334g blank
If someone have questions just ask me
Very soon I will do second board with another fiberglass

thats a pretty sweet press you got there. how did you do the concave?
isn't 2.5 cm of rocker pretty low?

sweet looking board. i always love the wood showing through like that, too bad the triax kinda diffused that like you said.

you next board should be pretty dope to

hi vol
is 8 mm of wood buoyant enough? does she stay afloat?

and the first picture: is the board symmetrical or there's photo distortion?

winds

:o wow! nice board!im building the same thing at the moment, except with ash core 7mm thick centre and 3 mm tips

please explain how you did the rails and inserts and also was the layup one layer 600gr/m^2 each side?

I think it's milky in appearance because it was a bit dry on layup, this might help you to get a clear finish next time http://www.laughingloon.com/epoxy.html it still looks really nice though! :D

wood core 8mm I hope enough because finally with fiber and epoxy layer is ~9.5mm, I make thin and flexy board special for freestyle
I took meter and check, YES :wink: the board is symmetrical, just photo distortion

ash core will be twice heavy :( check the wood destiny table http://www.engineeringtoolbox.com/weigt-wood-d_821.html
the rails I did bit wrong way but very similar like FNB viewtopic.php?f=107&t=2357086
the inserts like ski or snowboard http://www.skibuilders.com/howto/skicon/inserts.shtml
the fiberglass was triaxial 600g one layer each side
You right, layer looks milky, is few reason, maybe fiberglass to wet or just bad, maybe epoxy was not good for hot curing, next time I will do with another harder special for hot curing and super transparent fiberglass
thanks for good link :thumb:

I have had the same problem with tri-axial glass, it's tough to get the clear finish. I find 4oz S-glass or E-glass works better.

I order very clear glass from Interglas UD 320g and woven 280g, it's not the same characteristic like triaxial but we will see, the guy told is very clear glass.. maybe there's possible put woven glass to 45 like biaxial?

Does the board lose some of its rocker when you take it off the press? Looking at making my first board and am unsure how much a wood core will tend to spring back when released from the press.
