Boards break and crease, a fact of life in this lightweight era.
I have started putting carbon down the stringer until infront of the fins, then making larger football patches where the fin plugs go to overlap with where the carbon ends so it reduces any hinge effect.
How heavy are your shaped blanks before glassing, mine are on the heavy side at 1 - 1.2kg for a 6 0 shortboard. Although this is supposedly the lightest type of blank for the brand I use. Finished boards are fairly high 2’s so not very light, but nopt tanks either.
Boards will break or crease sometimes, but I know its never nice to learn of it when it happens to one of your boards.
As barry mentioned you could make the laps bigger - more area with 3 layers of glass and I suspect an extra 5mm of lap could make a big difference to strength… But of course all these things will add a bit of weight.
Orange foam? That would be the lightest foam US Blanks sells? Light glass job? 4 oz bottom and cut corners on top…Duh.
Why are you suprised that the boards snapped? Duh. I’m baffeled that you would build board with this construction…Ya they snapped…everyone I know would have snapped those boards in less than 30 days…
Hail all,
And once more into the breach ( BT )…
Totally buffalo’d!!!
So much for the wrapped arrimid…
I thought maybe the Appllecore stringers, NO
USB "team plywood worse, it is 2 me
the orange foam curse.
All I have learned,
IF, it is thin,
it is, back to RED. Fred
??? “Stupid” Just happened to be refreshing my memory and ran across your post again. Didn’t remember that I had somehow insinuated or otherwise called you “stupid”. Was simply stating that super light 4 oz. glassing schedules are not long term. It’s a trade off. Weight and or flex for strength. The desire for lightweight boards has resulted in new technology like V-Net, Innegra and various Carbon blend tapes. Lowel
Sorry lowell,
I stated at the start “I’m an older Poly guy lookin’ for some feed back.
Or a good flambéing for being so unwise.”
Further, no one but me said stupid.
No worries, just fustrated in the seach of lightness.
So stupid is easy for me to say because, hey I make test boards and hand them over to riders to test, or punish.
Momma sez stupid is, only I don’t want the rack boards getting a bad name.
So if there is a problem like this, some kid laying out good money doesn’t get burned.
USB orange isn’t working so well, so what is next???
EPS. Artic or Marko…
