alright, several have suggested keeping the glue inside the plan shape
so that while shaping the rails you don’t have to deal with the glueline
and the interaction between glue and foam.
Do you then come back and do something about the non-adheared
edge of the finished shape? or just let the lamination hold the railline
together?

Its not a problem. I just finished shaping my first EPS board. I used a standard 9" roller with Elmers white glue. I had already cut my 4’x8’ sheet down to a 2’x8’ piece and I used about 1/4 to a 1/3 of a gallon jug of glue. Rolled it on each piece and let them sit about 10 minutes and then stuck the 2 halfs together and piled on the weight for clamping & rocker. I let that sit for 3 days and it cured fine. Had no problems at all cutting thru the glue line on my rough shape. You can see and feel the glue line but its easy to sand with just a touch extra elbow grease. I took pics of each step of the process and will put a link up here in a day or two showing the steps I took.
Good luck with your board(s).
Or, as Greg Loehr suggests, use a light rolled-on smear of epxoy resin to join the planks, and sandwich in a 6" to 12" wide piece of glass cloth for a “stringer”. Bend during the cure to add in rocker.
Thats a good idea. Didn’t see that in my searching. My brother wants a 6’6" and I really didn’t want to use a wood stringer. Thanks for re-surfacing the info!

That’s exactly how I’ve done mine as well.
Thats because I have all your posts printed out and used them as great guidance! Thank you very much by the way!
I can’t wait to see your photos 
What shape did you build? If its another FP, I’m gonna think there’s a Home Depot design conspiracy…
Where can I find more info about builiding one of these blanks? I have never built a board before so I figure this cheap blanks would be a good start. I live in berkeley, California, where can I buy the necessary materials? Thanks.
Are you talking about EPS? I think these guys are getting there foam from Lowes or Home Depot. Make a dope board for cheap

Berkeley? Heck I’m in Oakland. Buy me a taco and I’ll take you through the whole thing
Foam & Elmer’s from Home Depot at 40th & Hollis. Foam brushes and sandpaper and stringer wood too.
Epoxy resin, hardener, and glass cloth from Tap Plastics on Alvarado, off Marina East, in San Leandro. Squeegee, mixing buckets & syringes, tints too.
Whole thing is less then $150, start to finish.
Hey Benny1, I’ll take you on that offer. I’ll include spanish rice and beans if you want
use the search for capability in the top right and search on
$14 blank
Benny has some great info there. It will also lead you to what others
have done similarly.
SF boarder if you are going to meet benny so he can show you the ropes on this let me know when so I can be there. That way he can get two tacos and only go through the blank making process once.
sounds like you SF/Oakland boys have a eps seminar in the making.
Wish I could come to your “Home: Connections: Events & Happenings”.
Why wouldn’t you want a wood stringer? A hassle or something? What kind of wood would you use if you were?
Mainly just to save some steps and weight. I’ve never tried it before so it will be interesting to see how it rides.
I can’t wait to see your photos

Sorry for the muli-replies. I’m an idiot. Can’t figure out the quote thing. I think it doesn’t like Mozilla.
Here’s a link to some pics Benny

Headhigh-sweet shape! The shaping sure is easy & satisfying with this light stuff…
have you glassed it yet? Go heavier than you think.
I use Mozilla too & usually its ok.
rik & sf - jeez, for two guys I ought to ask for beer Anytime it goes onshore for a couple days, give me a call & we’ll glue up some cheap foam.
Hey guys. When you glue up the sheets to get your rocker do you use the rocker in the middle of the board as a guide or the rocker at the rails?
In running through such a project in my head I keep stumbling on the convergence of bottom lines / rail bottom / and rail rocker lines. (By that I mean the mid point of the finished rail shape which would change if the rail shape changed along the board.
If I can get some free time to try one I was contemplating a thin horizontal epoxy stringer in place of the elmers and only when I saw the recent photos in this thread did I understand where I keep going cross-eyed.
Something just doesn’t seem right about the glue joint not following the rail center / bottom.
