So, i’ve been pondering how to keep the rocker perfect when bagging on skins for compsands.
Especially after the recent “Whats the most important feature ina surfboard” thread, where most people cited rocker as the number 1.
Previously I tried a bent backboard setup, and then tried just chucking them in the bag and racking the rocker round til it looked right…
But I just thought of a better way!
May have been done before, not sure, but i’m stoked on the idea.
No photos, cos I havn’t actually tried it yet, and Uni exams are taking up valuable board shaping time right now.
But heres the plan:
Hotwire blank - I glue the hotwire templates to either side of the square EPS block with dabs of contact adhesive, it holds them firmly, no movement. I use Ados Styrobond, it’s solvent-safe for polystyrene.
The blanks are exact thickness and rocker I want, from APS 3000, only a quick hit with the sanding block to take out hotwire wobbles.
So, I’ll stick in any required concaves into the bottom, then bag the bottom skin on with the templates still attached.
The templates will act as 2 stringers, keeping that rocker sweet!
Also any twist can be seen even easier than before, it’ll be more obvious because of the wide sqare block of foam.
Then cut out outline, rails, top skin etc.
Once that bottom skin is on, the rocker is pretty much permanently set for the next steps.
I bet you all already knew that trick and i’m lagging behind as usual…
