re shaping..

[bluesnowcone]

if i got all the mesurments, and front, back, side and diagonal veiws of a longboard fin, is it possible to reshape a bigger fin ( iv got one of the bic plactic fins, so thers no fiberglass, just solid plastic) using glass paper and files ect ect.

im a bit of a cheap skate, well im a 14yr old kid with very little cash

plz dont just tick a box, can u say y it wud be a bad or a good idea

[IdRatherBeSurfing]

worth a try!

[bluesnowcone]

yh, i some said no and some said yes, im gunu buy a nine plus cut away, then try rehaping my fin, then in anyone askes the same question, il have the answer atleast

[tomcat360]

reshaping it......bigger??

Look around on swaylocks about fin making from scratch. I think you'd probably have better luck. Going smaller isnt a big deal though, just make sure to re-adjust the foil.

kl, i was thinking of changing the 7.5" fin to a nine plus cut away, i was thinkinh all i nee to do is cut a chunk out of it then sand it down again

[bluesnowcone]

well, iv dont it, the fin looks good and its smooth, but now i just need to know how it surfs, this weekend should be good to test it out

Where are the photos???

[bluesnowcone]

oh il take some soonish, just gota get my board out of the van and then find a camera.

ok i cant find the camera, but il ask my dad when he gets back if he know what it is, the more i look at it it looks like a small cut away wingnut

guess what was ontop of the computer, im uploading the photos now

[bluesnowcone]

it looks ruffer in the photo that it actualy is, i couldnt get the inside edge a smooth curve, but i did my best, and for 2 hours work by a 14 year old, i think its quite good, and its as strong as it was befor i cut it, because i cut the most off the thickest part.

[kitesurfer]

Good effort though. I'd try and thin out the trailing edge on the middle section a bit more though so the water flows off smoother. You might find it produces abit too much lift and hence drag.

sweet, il get working on that after the weekend

[bluesnowcone]

ok, IT DOESNT WORK, I LEARNT THE HARD WAY, DONT DO IT, I REPEAT DO NOT DO IT UNLESS YOUR A PRO

[tomcat360]

hahaha, that kinda sucks when something doesn't work that you poured your blood and sweat into

But I'm sure it was a good learning experience, don't give up on it.

Should we get him talking to Chipfish?

bad luck, but at least you tried! better luck next time!

[bluesnowcone]

well i did learn something, dont touch things that work

[justloafing]

Good try
Now your going to be just a little poorer since you have to go buy a new one.

[bluesnowcone]

[dougirwin13]

Oh you can do it.

But you should spend a lot of time searching the archives on http://www.swaylocks.com/

I think if you follow KS's idea the fin wood at least be usable. It might not do what ever it was you were wanting it to do, but at least you wood have a back up fin.



You didn't really try it out without any foil on the trailing edge did you?

[bluesnowcone]

did do what ks told me to, but it sortof broke
