So I just wrote this in another thread, about designing the core for a fishtail on a snowboard for it to turn as a normal tail, :
"I got this beam calculating formula from a friend;
normal width x normal thickness in 3rd = new width (fish tail width) x new thickness in 3rd
I don't know how to write these matamatical numbers and symbols on the computer and my math skills are very rusty, but I think it goes like this:
Exampel with a 4 mm core in a 300 mm wide board turned into a 100 mm wide fish "arm" with same flex.
300 x (4x4x4) = 100 x (YxYxY)
Y = square rote in 3rd of ((300 x 64) / 100)
Y = 5,77 mm
It opens up a few nice design possibilities if it works out. In my calculations above, one of the "arms" should have the same flex as a normal tail. When on edge it would turn and feel like normal. But when doing a ollie, and using both "arms" at the same time the tail would be what equals 5 mm in thickness and a lot stiffer with more pop..! ? Yes yes I know that a fish tail on a park/pist board is a stupid idea, but a soft, smooth and goodloking ride with pop, ahh maybe not so stupid after all."
But then I had a drink and started thinking. And here is the idea. By splitting the tail in 2, not fish style, a single cut, it would be possible to get a stiffer tail for landings on a pair soft carvers. Skis or snowboard. And if you place that cut ofcenter, the outer edge/heelside could be made softer than the inner/toe while having a rock solid landing platform. By doing it with a single cut instead of fishtail it would be possible to make twintipps.
If you wanna go extreme, cut two cuts and divide the ski/board in 3 pieces after calculating the new core thickness needed. Does it work you think? or why not?

Haha, I might!
soft for turning, stiff when landing or going strait down.
I didn't think of split tails. I was thinking of something like this:Split tail in a ski was done a long time ago by one of the big companies. I forget which company. A friend of mine had a pair. I don't know what purpose of it was back then other than to be different. The idea came and went.

They're reckoned to be the absolute dog's nadgers by those lucky enough to have ridden one. I do not feature in that group.PTTR wrote:Fantastic! yes, that is what I was talking about. Has anyone tried them? does it work? Stiff and soft at the same time. A snowboard or a pair of skis on half a pill of viagra.
Coda made a split tail skwal, too, don't know if they experimented with split nose.

First try.
a pist-turn-carve-park-play ski. 170 cm long with 10 meter radius. Yellow base top and bottom and purpelheart sidewalls. Aimed to get the core a little stiffer than normal before the cut = a little softer than normal on edge but stiff in landings, but I am afraid I made it too soft. we will see, the radius is super short so they will need to bend, maybe it's good they are softer. Will test them on sunday.

AHHHHHHHH
like riding a rollarcoaster! The yellow fellow, tom bobadillo, supercarver.
In retrospect I probably shouldn't have cut the tail but what a ride! I've been away for a week of skiing and have lended them out to everyone. People return with bruises and smiles. A split second out of focus and the skiis are behind your head, trying their own version of a flatland linconloop.
