Grain Surfboard Laminating Tutorial Entropy Resins is A video tutorial on wood surfboard laminating using Entropy Resins’ Super Sap CLR epoxy resin over a Grain Surfboard.
Super Sap CLR is a clear laminating and coating epoxy resin partially derived from bio-based resources, with a dramatically lowered carbon footprint when compared to traditional epoxy resins.
The CLR system with CLF fast hardener is made with UV stabilizers to resist yellowing, is blush free, and relatively quick working times for wet layup laminating of surfboards, boats, and other DIY or industrial applications.

The Asymm Surfboard by Mike Lynch
This board design had been stuck in my head for some while and I had it drawn out forever but not until I took the idea to my buddy Tim Crozier at Black Bird Surfboards was I really able to make my dream a reality.
The founding concept of this board was always to have a swooping rabbits foot tail so that I could really pay tribute to what a true asymmetrical board is; two of your favorite boards in one, separated by a height and width difference.
After deciding I wanted to go quad on the right and twin on the left, it came to that the board should be 5’11” on its longer side and 5’4” on its shorter side. Heights that were derived from a favorite Mini Simmons and a favorite diamond tail quad of mine. I wanted the speed and drive of a Simmons, but the turning radius of a tight tail quad.
I threw in a deep concave that banks off of the rabbits foot and two off set fcs trailers and all-of-a-sudden we had a board with 2 different shapes built into it and 7 different fin applications.
Couldn’t have done this without my buddy TC, he’s taught me so much about shaping its just incredible, the rails on this board are truly stunning thanks to TC’s eye.
We won the compliment of ‘Best in Show’ for this board at the Boardroom Trade show 2014. Stoked.
David Barr has introduced “Shapeshifter”, an innovative surfboard removable tail system.
There’s a wide range of surfboard tail shapes. It’s easy to get confused because, in some cases, the variations between them are subtle and marginal.
The most important tail shapes are squash tail, square tail, thumb tail, rounded pin tail, pin tail, baby swallow tail, swallow tail, bat tail, and wing tail/tail.
Depending on the ocean and wind conditions, you may pick one or another. David Barr, who has been surfing and shaping for four decades, is developing a new removable tail system that will shake the way we blend fins and surfboard shapes. Basically, we will be able to switch from a pin tail (big wave surf conditions) to a swallow tail (small summer waves). At the same time, we will manage these choices with a proper fin setup.
The “Shapeshifter” comes with six different tail shapes: diamond, swallow, squash, round pin, asymmetrical right, and asymmetrical left.
Is this the world’s most versatile surfboard?
I love every aspect of shaping except turning the rails.
Not only are they tedious, but you got to do them twice and try and get them symmetrical.
A buddy of mine once told me to take a finished board with rails that I like and use them as a template. He recommended cutting out some foam and shaping the rail into the foam and then to use that foam template to guide the shaping process. I thought it was great advice, but three years later I still haven’t done it.
Rails, I really dislike them.
I still use the same technique for shaping surfboard rails that I leaned about a decade ago in JC’s shaping DVD. I make two rail bands, one 2 inches from the edge and another 4 inches. Then I mark three spots on the rail itself, all between 1 and 1.25 inches from the bottom. Then I use my planner to shape those bands into the deck, here is the process in more detail:
(we got a rad link to a detailed look at this process at the end of the article, keep reading)
Scientific? Hardly, but kinda,
I wish they had a CNC machine just for shaping surfboard rails, I would buy it for sure.
Or even better, I wish there were dudes that just did rails and you could open up the yellow pages and look for them just like you look for a plumber. For $40 you could call them up and they would come over and finish your rails.
But no such luck, just me and my tools and those damn rails.
I did some research on rails, surfline says, “visualize and plan how much of the middle part of the rail you will leave untouched.”
How about the whole rail?
I should try that, make a board with no rails . . . I wonder?
Ok, that is a ridiculous idea but I had to say it.
Back to visualizing I guess, here is the Surfline article if you want to check it.
In another article Greenlight Surf Supply has decided to just simplify rails and suggests that there are only two: boxy and knifey.
Dudes, I wish it were that simple.
But I get where they are coming from, essentially what they are saying is that a knify rail cuts into the wave and a boxy rail floats on top of the wave.
Ok, I get that and agree.
Rusty also breaks shaping surfboard rails down into two types, 50/50 and down-turned.
Finally, someone gives some riding advice.
Rusty says about the 50/50, “this type of rail lacks a sharp edge on the bottom, water can more freely flow out from the bottom of the board as you plane down the face of the wave. This buoyancy and a lack of edge make a board with rounder (50/50) rails much harder to maneuver.”
He goes on to talk about the down-turn’s sharp edge, “holds through into the tail and helps to capture the flow of water from the nose and keep it underneath the board so that it creates lift as it runs against the fins in a tighter manner.”
Bravo Rusty, you-da man.
Watch this video as he schools us on tail shapes and rail design.

Ok that it for now, go get yourself a blank and try one yourself.
