Hi,
I’m not a glasser or shaper (i just started doing my own repairs) but as a surfer who doesn’t much like pulling back i have an inherent interest in board strength ie snappability.
for my small-med all rounder boards i usually get 4ozx2 on the deck and 4x1 on the bottom. i sometimes get 4ozx2 deck and 5oz or 6oz x1 on the bottom if the board is for heavier waves. in the past i’ve had boards with 4ozx2 on the bottom as well, but these are noticeably heavier.
i’m keen to find a better solution for increasing strength without limiting performance, and i’m leaning towards more glass on the rails as opposed to more glass on the bottom and/or deck.
i’ve read about tubular strenth, and some of the modern day sandwich techniques all seem to boast that their strength comes from the rails, so why can’t we tap into this strength using traditional materials?
Firstly, lets just confirm that i understand how boards are generally glassed by the everyday shortboard shaper using the above diagram (stolen from another post):
firstly, bottom layer of glass laps up to E or D
secondly, both deck layers of glass lap down to B
Is that correct?
If that is the case, would there be any benefit in having one or both deck layers lap to somewhere between A and B instead of ending at B?
Now for adding some strength, i’ll describe what i mean using the diagram again:
bottom laps to E
1st top laps to B
2nd top labs to B
THEN an extra layer of glass (possibly 6oz) laps from D to A (or E to A if no weaker)
I’m hoping this would add similar strength properties as an additional layer of glass on the bottom (lapped over the rail).
What do you gurus think of this theory?
Anyone tried it?
