Buckle Buddies

Eh,

I’m an older Poly guy lookin’ for some feed back.

Or a good flambéing for being so unwise.

Last year’s batch of beta boards have held up well enough

That two were handed down to some

Deserving younger riders

Both boards, different riders

Both buckled at the nose from hitting the bottom.

I say the “Y” generation, as in why do you have ride to the bitter end?

Anyone seen anything like this?

IMHO the Rasta should have snapped!

Both boards constructed with orange foam

Single 4oz. D bottom single with ¾ deck patch 4oz. D (deck)

The first 4mm ply stringer with a thicker nose.

The other “Rasta” apple core stringer

Same glass schedule.

Thinking if these boards had heavier glass jobs

They would have snapped, as in stiffer.

BTW that glass schedule was last years.

This year’s stuff is a lot better.

Thanks for lookin’ in….

How quick people forget that before Clark closed, almost all shortboard blanks made by him had 3/16th stringers.

Unless you ordered them differently.

Boards had become so thin, the noses were snapping like crazy.

1/8th has become the norm now.

Even with T-band glued stringers they still snap.

Stuff 'em into the bottom of the ocean and they’ll do that sometimes.

Try making the laps wider in the nose area when cutting them.

Its really not much more work.

When the nose thickness is about 1", there’s really not much stringer there to keep them from over-flexing.

Matty, did you notice they both are buckling where your glue lines end?

Kinda like where tails snap off in front of the fin boxes.

Boards break and crease, a fact of life in this lightweight era.

I have started putting carbon down the stringer until infront of the fins, then making larger football patches where the fin plugs go to overlap with where the carbon ends so it reduces any hinge effect.

How heavy are your shaped blanks before glassing, mine are on the heavy side at 1 - 1.2kg for a 6 0 shortboard. Although this is supposedly the lightest type of blank for the brand I use. Finished boards are fairly high 2’s so not very light, but nopt tanks either.

Boards will break or crease sometimes, but I know its never nice to learn of it when it happens to one of your boards.

As barry mentioned you could make the laps bigger - more area with 3 layers of glass and I suspect an extra 5mm of lap could make a big difference to strength… But of course all these things will add a bit of weight.

Hope all is well with you.

Just re-read your post,

Where did the deck patches end? near the buckles?  could be getting an un-equal amount of flex towards the nose up from the deck patch.

Or could just be bad luck and heavy surfing, boards hitting sand can end badly no matter how the board was glassed.

I was also going to ask where the deck patch ends, and in what manner does it end? Straight across? V cut or some other nonlinear cut?

let’s see if they can mess this one up!

Looks good!

I would be thinking denser foam and epoxy resin, that’s just me.

Thnx for the post-stressed comment, I finally get it.

8

Orange foam? That would be the lightest foam US Blanks sells? Light glass job? 4 oz bottom and cut corners on top…Duh.

Why are you suprised that the boards snapped? Duh. I’m baffeled that you would build board with this construction…Ya they snapped…everyone I know would have snapped those boards in less than 30 days…

All due respect Ray!

Team boards AKA thru aways.

Very light 4,4/4

I am suprised they didn’t snap!

Moving on now, even test pilots get the new glassing schedule.

 

10

You have to expect buckles and snaps with a 4 oz. glassing schedule.  Just part of the deal.

11

LOL Lowell!

Not stupid just pushing my limits.

The buckled boards  where “last years”

Since moved on to a new schedule. 

So far they are holding up well.

Eh, I am lucky my boards get surfed HARD!

Just R&D for an old hack like me…

I love your work Matt. In my world I can’t have “team” boards… The next few will be for me. Some EPS, some poly. 6 bottom and 6x4 top…

I’m seeing too many problems with crushing / feet dents / water intrusion… take it from there…Ray

Defiantly not calling anyone stupid.  Just stating the obvious.

14

Hail all,
And once more into the breach ( BT )…
Totally buffalo’d!!!
So much for the wrapped arrimid…
I thought maybe the Appllecore stringers, NO
USB "team plywood worse, it is 2 me
the orange foam curse.
All I have learned,
IF, it is thin,
it is, back to RED. Fred

??? “Stupid” Just happened to be refreshing my memory and ran across your post again. Didn’t remember that I had somehow insinuated or otherwise called you “stupid”. Was simply stating that super light 4 oz. glassing schedules are not long term. It’s a trade off. Weight and or flex for strength. The desire for lightweight boards has resulted in new technology like V-Net, Innegra and various Carbon blend tapes. Lowel

Sorry lowell,
I stated at the start “I’m an older Poly guy lookin’ for some feed back.
Or a good flambéing for being so unwise.”
Further, no one but me said stupid.
No worries, just fustrated in the seach of lightness.
So stupid is easy for me to say because, hey I make test boards and hand them over to riders to test, or punish.
Momma sez stupid is, only I don’t want the rack boards getting a bad name.
So if there is a problem like this, some kid laying out good money doesn’t get burned.
USB orange isn’t working so well, so what is next???
EPS. Artic or Marko…
Aloha
