6'06" EPS+Epoxy, should we add WOOD ?

General Discussion
1

hello all,

I am currently working on a thruster 6.6 * 12.5 * 19.5 * 2.4 * 14.6 small wave groveler with little rocker and some slight concaves. It is a 2# STRINGERLESS EPS construction with 24oz top + 1 5.5oz thick weave bottom with RR Fast Epoxy.

SHOULD I ADD WOOD TO THE FINISHED SHAPE?

YES = wood should add life and spring to the board

VS

NO = The laps that are quite big should provide enough stiffness and spring

Thanks for any advice

all i can say is i have built one 8 foot board without stringer no wood, just a lot of fibre glass and epoxy, and it flew and turned well, but that could also have been the shape?

I think not, and that’s based on my asking someone else about adding in stringers–he said he had a 6’6" stringerless EPS board which he said was great and encouraged me not to add a stringer. Said he had 5 layers of glass around the rails by the time he finished and it was great and to enjoy the flex.

I’ve seen guys talking about how stringers are outdated tech, but I’ve also heard a local (old man) say you’ve got to have a stringer – I think the advantages are too compelling not to try it without one or wood skin before you surrender

I also think wood skins probably cut down so much on flex that you really ought to try a shortboard without first

Whoa–just noticed your light glass–add glass-- report what happens/how you like it.

This has been … my two cents.

thanks

these 2 cents are worth a lot now,

I know many board builders who swear by the stringerless epoxies. Go for it you may dig it. I plan to make one for myself.

There are many experiments going on right now with this technology. Clyde Beatty has been making them for a long time with great sucess.

The glass on the rails give it it’s strenght. Kind of like the Firewire. However they are much easier to build.

A stringerless board glassed that light will buckle or snap within a few sessions.

I speak from experience.

Hi Janklow

quite a late reply

did 4+6 bottom

and 6-6-4 top

a standard plus, so it seems

it has little flex, very little

with extra overlapping laps

it goes excellent for the rider who rides it

she loves it, see attached aps shape

i did take down lots of thickness in the tail

once you get to the middle a bit more (as she does a lot) it flies

if not, it is pretty average to turn (mistake = copying the flyer set up by merrick)

i should have done the fins further up the board

i just read someones opinion that it has too much hip

anyway

the rider loves it

and the board has very few dents

no cracks

no failures

everybody happy

next board will be a 6.06 again, wide ass nose, flipped tail, single, 3, 2+1, or twin with 2*4 bottom and 4-3-4 top, less full rail wraps, RR 2020 and Fast hardener

if you are interested in pictures of the board let me know

cheers

"did 4+6 bottom

That’s a really heavy glass job for a board under 7’. I’d like to hear more about the weight and how it rides and feels. Not so much interested in exact weight but how it feels in your hands compared to other boards. How it moves in the water…

Would you do it again??? What would you do different next time? Are you sold on stringerless? Have you considered plastic stringers (Komitex)?

I’m currently riding an EPS board with a homemade Balsa stringer. I’m looking for ideas for the next step …

I’m so blown away with what I’ve learned about rocker from Swaylock’s…WOW!

Hi Stingray

Next time i will make a 6.0615.520.2514.52.20Thick

Thinner thus!

With the volume up front, thinner tail. It should become an up front rider, possibly able of cheater 5s with the rocker flatter up front, in the 3-4inch range, with 2.5-3 inch in the back. i did one board with lot of rocker and vee in the back comboed with flat nose rocker, and you can gain speed up front and kill it on the back half. so that is why. YOU HAVE ROCKER IDEAS for such a board? you know, a cheater, but still ripping it in thruster, twin, or any other combo, i think i will skip the single box, looking for that movement…

Thinner rails, boxy, small rail apex with pretty hard edges all over, but with thin enough of the board able to bite and drive-lift.

i am considering maybe 2*3 bottom, with wood inlay on top, so that i still have little glass, but no denting, so maybe 3oz’wood’3oz top, with thick hot and gloss.

-the rail wraps will certainly be there, thinking of wrapping 2 top layers onto the bottom, but no bottom laps on the top, which should promote the construction to move around more easily (not using that fancy word!)

maybe i will use a very stiff epoxy for the wood-glass composite, and bake it off, have mega’stiff top.

========

considering the 6.06 i did make,

including 3 fins, wax and leash, lots of spray paint (did you know that the tuflite paint goes super well on eps?!) it weighs in 4080 grams or so, it has the glassing mentioned in combo with 30kg/m3 eps by www.atuacores.com

the board has all the rail wraps but one, meaning 4 of them, and going about 2 inch over top, and like 4’5 on bottom, i.e. the max width, not nose and tail measurements

i am going to lie down, my head hurts from yesterdays jazz festival still.

PM me your e’mail and i will send the aps file of this 6.06 groveler since i do not know yet of a way to share all my files yet without compromising my computers well being

cheers!
