So. Cal.
Xmas present:
black and orange G10. Now I just need to learn how to foil some fins.


Supposed to look like this when foiled:
do different colors change any physical properties of g10? i'm also wondering how hard it would be to find the same colors that site has but in bigger sheets.cool looking stuff you found <img src="/forum/images/graemlins/applause2.gif" alt="" />

Greg ,

What does g-10 do that normal glass fins wont ?

i guess i am saying is that if you made your fins out of normal fin panels instead of g-10 ?? <img src="/forum/images/graemlins/shrug.gif" alt="" />

I didn't see bigger sheets. I had to order two of these to get a side fin and trailer on each. Ended up being about $50.

moved my GG front fins up past the dot today for the first time . its official , you can have 2 different boards in one.

one the dots my board is lights out fast fast fast , seldom slides , loves power turns . up on top of the dots it becomes a submissive servant , ultra forgiving ( my only complaint with the g-10's is that it was not forgiving ) super easy to whip little top turn snaps then continue down the line , skatey , and even more front foot friendly .

slight decrease in down the line drive , but today was not about g-land speed runs anyway .

Yes different colors do affect the G-10. Some colors have fire retardant in it for heat resistance. Because of that when it warms up it stays stiff. Hard too foil though. Some of the colored G-10 uses fabric for the color it is not fiberglass. Tends not to be as stiff at tip of fin.
Colored G-10 or G-10 with carbon are usually only sold in small sheets because they are limited run production done on small presses. Natural colored G-10 is done on 48"X96" presses. The presses are huge and expensive. A cool way to make multi colored panels is to buy thin G-10 of different colors and sand with 36 grit and glue them together with epoxy.

u dont like glass flex m5's ?
just got a new 6-1 bourton hpsb that came with glass flex m5's. i think i hate them. getting zero drive/response in average lined up waves. traded the fronts with the AMs in hh+ waves, and voila heaps of drive but chitty turning.

need to find something in the middle i think.

k2.1s maybe? haven't had an fcs board in ages, and with the extent of their range, hard to know where to begin.

Leave the Am's and adjust the rear to free it up for turning.
Start with moving the rear slightly forward then changing the fin to another template - size.
unfortunately, they're not the fusion plugs <img src="/forum/images/graemlins/frown.gif" alt="" />, so i'll throw in a smaller rear fin and see if that frees it up alright.

might be that i need to just get some fins in a stiffer material as well.

i'll check out the pc7s, <img src="/forum/images/graemlins/cheers.gif" alt="" /> for the advice!

for gooooood waves and ok ones to you cant go wrong with gregs fins .

even if you have the old style black plugs his fin tabs are smaller and allow fin tuning . it should also be noted that his fins fit flush , all 3 of them , in all boards !!! novel concept <img src="/forum/images/graemlins/socrazy.gif" alt="" />

for stock fcs fins ,

drivey fins would be the AM line 1 or 2 , pc is better than gf. you can get glass ones from true ames .

next up in drive , the mayhem and simon anderson.

honorable mention would be the stretch fin in pc and the TP-1.

sice your in the UK the CB-3 could be a great option for drive , and they are pg to .

all fin sets from fcs can benefit from a M3 center fin , it can really loosen up a board off the top and " seems " faster with less effort .

do thicker foils have more drive at lower speeds due to more water attachment? e.g. easier to swim the board off the fins at lower speed?
Havoc,
you seem to understand and be educated in things far beyond my own personal understanding, but just thought I would offer the Thick fins vs. Thin Fins thread at Swaylocks
you might be able to make head and tails of it
for me, its like I’m Alice and I just went down the rabbit hole. <img src="/forum/images/graemlins/drowning.gif" alt="" />
not light reading (for me)

Keep track of your total fin cost tuning this board and report back when done.
so far £0. waaaaiit, are you suggesting... custom fins might be cheaper in the end? <img src="/forum/images/graemlins/smirk.gif" alt="" />

seems logical, sure why not.

ship to the uk much?

yeah, i tried some am1s i had laying around in some pushier lined up waves and got all the drive i could want. however, when it came to putting it on rail they felt twitchy and too much fin. perhaps i could substitute the m5 rear with an m3 like you said to free it up. could be as well that the twitchiness at higher speeds was due to the glass flex material bending all over the place, and a stiffer fin would have eliminated this problem.

the last 3 boards i owned were customs with custom fins, so haven't had to think about it for a while. i generally get a board every year and surf it to extinction.

thanks for the tips!

Broke my bamboo tab from the outside?! the other day. I thought my board was a little bit loose on fs cutbacks, but I thought I was just being a kook, as usual. Got out and noticed my fin was loose. I didn't think the outside needed any strength, but I guess I was wrong. I glassed the inside 4 x 4 oz + 1 CF layer, but only one layer on the outside. Now they're going to be glass ons. Back to my G10.

I kinda look at breaking a fin as a badge of honor...

BTW I found FUN setup for my Coil Springfish today
Glass Occy (FCS Occy Side Fin Size: Side Base: 4.62 in. 118 mm; Side Depth: 4.68 in. 119 mm) copies from Indonesia for the fronts and old school black material FCS-tabbed Future Vector 437s for the rears
