How to make a stiff TT softer

Postby FabsPH » Thu Apr 02, 2009 11:22 am

I have a custom TT, but I made it too stiff. I was wandering if I could make it softer, by:
1: heating it
or
2: heating it in a press and bend it and let it cool
or
3: ???

Pretty sure nobody has done it, but some home board builders might have fiddled around enough to have an idea.

PS: it's got a wood core
Also, by custom, I mean I custom ordered it .
I don't want to scrap this board, love it, but too stiff .... kick ass for flat water..not so great in waves.
Was my bad for custom ordering.

If you round the tips off, you'll have a softer ride in the waves, better for your knee too...

maybe ask the shaper who did it? He knows his layers and could be of help.

Why not try some REALLY soft footpads?

It's probably more of a case that the rocker line and outline is not right.
You can make a stiff board ride smooth and a soft board ride hard all depending on design.
If you take a bad design and stiffen it up you really gonna notice.
That's why most production boards are so flexy, they can get away with bad design, with a rocker line that is changing constantly :lol:

I don't think you be able to soften it

The only way of modifying flex is changing the moment of inertia (I) of the boards cross section. On a finished board, the only way to achieve this is to either weaken the laminate to reduce I or to build up the aminate to stiffen the board. Increasing flex can be done by sanding away part of the laminate; I would suggest to start at the bottom since laminates work better in tension than in compression. But you can also quickly reach the fibers yield strength and risk breaking the board.
I must point out however that all of the stated above is also right. A boards behavior is a combination of many variables, modifying just one of them might not produce the desirable outcome.
It is rare to find stiff boards that have a set of variables that work good together, If you have such a board, I would suggest not to mess arround with a winning combination and get yourself a second board for waves.
There is NO board that does is all and does it well, is allways a matter of compromize.
If you want a smoother ride, try
- reducing stands: a board behaves like a simply supported beam qith cantilever tips. Reducing stands shortens the distance between the supports and increases cantilever length. This will increase the bending moment and increase tip flex.
- softer pads: try LF's. Personally I don't like them, I feel I loose feedback from the board.
- larger fins: thay do wonders in waves.

Easy : 3 weeks Macdonalds , gain 20 pounds , your board will ride much more softer with all that add on ... :idea:

Why not use your board for flat water then ?

And have another one for waves/chop ?

Then you get the best of both :D

Pads wont help at all IMO, if the rockerline is too stiff for choppy conditions.
And as said - the outline and shape is far more important than flex, regarding how "soft" a board feels 8)

Just an idea 8)

Thanx for all that.

Pads don't make the board "softer" btw.
By softer I mean, more flex.

Also, sanding down the board is just crazy. Would maybe work if it was a glass board.
I was just wandering if there was away to heat it and re-shape it.
Most likely a stupid question, but you never know.
Maybe I should just try it, and who knows... maybe I come up with something incredible.

And yes, i use it just for flat water instead,..... if I was into that. I love to mix it up in one session. Waves and flat. Where I go kite, I got both . Doing one thing is boring to me, and switching boards during a session is not what I am looking for.
I talked to the people who made it already and it was my mistake to order it stiffer.
I wanted it stronger, so that's what I got.

Also, cutting down the tips will not work out at all, Tut (alex) !

Maybe a steam box will work. Or it might just melt it.
Or, I just get used to it.

Epoxy, polyesher and vinilesther resins are thermo set, not thermo plastic. So heating it up will not work, worst case scenatio is your board going up in flames.
Best bet is to go with another board.
