.....some PVA's (most of them) are not waterproof.....I use DorisExpress (German), and they make an additive that waterproofs the glue ....maybe the Qcell/cabosil will waterproof the PVA ?......although , Ive never used PVA to seal the actual shaped blank...........ask Huie , he got more moves than a chessboard.
for sure Yorky.....epoxy/Qcell primer and epoxy lamination is a combination that's hard to beat......and the Qcell/epoxy prime coat sands nice with a 320 grit before the lam , and still keys in solid as.......I wipe the prime coat over with a fine sponge , after squeeging it in , especially around the rails , to keep it nice and uniform all over......what density is the EPS ?
I'm interested in your thinking about the parallel rails and deep channels. In my mind the parallel rails and wide tail will aid speed and the channels will tighten up the tail because they'll slow down rail to rail response. Do you have extra rocker or is this a small wave speedster for above the lip surfing? Or have I got it all wrong?
There is quite a bit of rail line rocker between the feet.
Cause It's got a deep single concave plus the double down the middle and parallel rails, the extra rail rocker is an important thing i'm thinking.
This board has no tail flip, it's a constant ark (rail line) rocker running off the tail.
I used the 'Golden ratio' formula for the rail line rocker increasing toward the nose (the nose flip rocker was taken from a rocker that I got cut out of a sector of an oval)
I'm really relying on the wing, tail shape and the foam taken out from the channels to compensate for the consistant rail rocker out the tail.
The bottom shape is a combination of arks flowing through the channels and out of the tail.
I didn't expect the middle concave out the back to be so deep, but the radius ark (I chose) dictated the depth.
Red your statement 'the channels will tighten up the tail because they'll slow down rail to rail response.' It feels correct but can you elaborate on this more pls (mainly slow down the rail to rail response)

You got it all right Red, as far a I know.

Damn that "Future of Sways" thread. This post is what it's all about. Brain fodder for sure. Thanks for your detailed response. Made me think about a new board in the quiver for Sri Lanka in June.
In my experience, heavy channels in the tail tend to hold the tail flat in steep waves. The result for me has been the tail getting sucked up the face in the tube because I can't seem to get that rear edge in. So I extrapolated from that. But a surfer of your talent should be able to stomp on that tail and make it obey!

laminating in epoxy... I always used epoxy and qcell to seal in the past, might go back to doing that.
...Idea was, well I got all this glue haha, and It's cheaper.
what would you do? ditch the glue in pictured??
Huie will be back in a few days going to seal it soon

vh grade foam.
the sponge after squeeging is a good one.
already jumped in and used the pva glue i have.
Start again
cheers huie
now retired
Wood glue is kinda yellow in color isn't it?
White Elmer's glue dries more clear.
Board is looking great by the way.
Been painting a bunch of Tomo's lately.
Similar tails.
Lots of concaves going on there.

By memory the last one I did with the glue seamed clear... I'll roll the dice and we'll find out.
Yeah lots of concaves, there everywhere.
might throw a couple of deck channels in too haha.
Thanks

I want this board to be an allround shortboard.

So good it's worth repeating.
