Perimiter Stringers

General Discussion
1

I’m referring to “both” types of perimiter stringers, inset and on the rail. Doesn’t this idea encourage shear along the length of the stringer simply by running the length of the board? One way to discourage lateral(?) movement is to bend or put curves into whatever else you are putting into the board bar the foam right? But the way I see it a perimter stringer only curves one way, from left to right. Aka two dimensionally, something that a surfboard is not. You engineers out there should be able to confirm if I am right or wrong. Cue Huie any time now…

engineers are like totally square dude. they cant dig on it cuz they cant feel the magic cuz they dont belive in it.

its the realm of drug fcked artists . radical free thinkers and hip cool cats is the lot of surfing design

thats why surfing adds can bulshit till the cows come home and sheep just lap that shit up

cuz even if a engineer proved it otherwize no one gives a rats arse cuz hes a DORK

Hold On! (Fart Noise) Now, What Were You Saying?

Only 2d with no curve, no rocker, no curved surface outside, inside of the stringer.

Building sheets of “surfboard” plywood?

is the persecution complex something that kiwi’s are genetically predisposed to?

It’s good to see that I’m not the only one wondering what’s up with those guys!

Maybe its that they’re heading into winter. Maybe their favorite sheep won’t give 'em any lovin… But boy! you kiwi’s sure are coming across grumpy!

Hey Dean

Greg Loehr might be a good guy to ask.

I only have limited experience with “perimiter” stringers, or “parabolic” or whatever else they might be called.

I have yet to experience any substantial benefit or drawback.

They are a pain in the ass to work with…but I’m sure that others with much more experience than I, would argue they are well worth it.

And who knows…maybe some would say they are not.

We originally did perimeter stringers to make flex patterns more stable and consistant. It also was perceived that they would add perimeter weighting to the board which is an advantage. Both of these aspects have been proven and while there are differing opinions on which rides better, perimeter strung boards certainly have their fans. I personally find them to ride great and especially when high density rails are added. More drive. I also don’t find them at all hard to shape.

Sure Greg…but not all of us are GREG LOEHR for cryin out loud! LOL

im not a kiwi

im from the sunshine coast the capital of payingout and BS

so i can recognise easily

i know when smarmy twats think they got one over me

I for one am a huge backer of the perimeter stringer. I did a whole series of boards based on a 7’9" favorite shape (see old post from 2006?) I did 3 Poly 7’9"s, 2 EPS 7’9"s in 4 oz cloth, 2 EPS 7’9" in 6 oz cloth, 2 EPS Perimiter 7’9" in 6 oz cloth, 1 WMD 7’9". I don’t know the math of why the perimeter works, it just works. I also see the benefit for guys who weigh over 200 lbs, you see for guys over 200 lbs semi stiff boards is a good thing. Getting a board to flex isn’t difficult when your slightly heavier than you average 16 year old surfer. Now if I take a EPS/Epoxy shape with a light glass schedule, it’s a fun board to ride…but it will eventually buckle under the weight, or fatigue and break, or delam and break, or just fall apart and break. Perimeter stringers add strength and return flex, which is good for a bigger guy, I have yet to break one of my perimeter stringer boards.

**The harder you push the perimeter stringer board, the more alive it becomes. Now take the next step…put a wood skin over the top, and use a lot less fiberglass. As Greg Loheier says, wood has a fantastic flex to strength ratio. **

My world was like this:

  • **Poly, PU/PE was great to surf, fun etc, didn't know any better**
  • **Clark dies, panic..looking for foam, tried EPS. EPS is different to shape, but loosing weight on board is fantastic, especially for the mid size sedan type boards 7'4-8'0**
  • **Kept breaking light weigh EPS boards, so I start glassing heavier with 6 oz, some of the magic dies with the weight.**
  • **Perimeter stringer brings the strength of the board back, while dropping the glassing schedule. Magic is back, and boards are more durable...except for heal dents, and rail crushes.**
  • **WMD comes along and solves the golf ball deck problem, while adding more twang to the board.**
**I think the NZ guys all have Mad Cow disease? I think they just need to go seal bashing and learn how to loosen up there back swing. I think there gripping there club too tight. If you grip the club too tight it will cause you to slice a bit too much. Helpful hints from resinhead.**

i agree resinhead those kiwi are a bunch of sheepshaggers and the women are woof woof if you know what i mean.

i only came over here to make me feel smarter and for some surf

btw im just a dumb aussie but i could have told u eps without skins was crap 3 years ago

Have you ever tried standing barefoot in a fresh cow turd or tackling a sheep Resinhead? It beats the pants off swinging seals while practicing your backhand. You should come to NZ and try it. Baa…

15

No way…blind folded in a 20’ x 20’ room, surrounded by 30 foul mouthed, anchovie belly howling California sea lions…and a 36" Louisville Slugger K55 Model!! Now thats a good time!

16

California love baby, California love.

17

Uhhhhh…resinhead

I don’t really want to ask…but I have to know.

How on earth do you fit 30 sea lions in a 20x20 room?

And I’m guessing you use baseball catchers shin guards to keep them from ripping your knees off?

Just wondering

What!!??? That’s 13.3 sq fet per seal? So its a little tight, thats what makes it fun. Heck I’m wearing a hocky mask and full HHansen slickers?
