glass on fins

[skansand]

i broke a keel fin off at seal on monday and just started glassing it back on...ive got some light matting glass on boths sides and a single layer of 10 ounce with a few strands of kevlar to fill in the cracks between the original glass almost under the fin...all done with solarrez..how many layers should i put over this????......Seal beach tommorrow....anyone down?

[skansand]

- about seal beach
if its the wave i think it is (seen some video of it )
looks super fun
Would love to surf it sometime if i ever came up that way

[skansand]

too late.....already sanding first lamination....kinda flexing too much still....ill do what i can to fix it but its this way till it breaks again...ill just bring my BZ tomorrow with me just in case.

broke the other keel fin today at seal.....so shallow...thinking im gonna pull off the other outdated keel that i glassed on last night and start fresh with a quad setup......what do you think???

[skansand]

spongergonkneelo...have you seen The Inside?.....one of the best bodyboardingvideos of all time.......it has some seal in there....(when they throw bread into the shorebreak from the pier to get seagulls to dive for it only to get slammed by the wave.....that bird got barreled.

I guess it was fate that i broke the keel fin today becouse right afterwards i was sponging Peak Of Death and had a 5 second barrel...hands down the best wave of my life.......8' high and throwing at least 5 feet in front of me ........square........along with 9 other in-n-outs......beutiful day....empty lineup

well so i fixed a couple dings with 8 ounce yesterday...so thick that when you start sanding it totally clears up...you would never have known there were dings there.....so could i glass those keels(trash the quad idea) on with 8 ounce?...i have so much of it and am trying to save money to buy a roll of 4 oz s-glass and a gallon of epoxy rez....so i figure ill buy a big ding-all sanding resin tub for now and fix that 5'2 so i can get it back to my friends dad.(hes in no rush as he doesnt surf anymore but i feel ive had it for long enough.).so would it work ?? could i do it with 2,?3,?4,? layers on each side?

I agree with beeline 8oz seems like over kill and more work sanding later. I have used one strand of fiberglass rope or equivilent of 6oz
fiberglass unwoven on each side of the fin. Then two layers of 6oz one 2" wide x length of base of fin. second 3" wide x length of base of fin
The final layer of 6oz glass is cut a 1/2" larger than profile of fin with about 2" more on bottom. I hope you can understand this.
Ive used this method ever since I was taught it. Iv'e never had a fin failure due to fin lay up. Coral reefs and fist are another thing.
The last time I used this system of lay up was on quad boomerang fins
no sign of stress yet.

hmmm can i use fiberglass rope with epoxy resin? i busted a fin off of my epoxy quad and put off putting back on till now.

Sorry didnt know its an epoxy board I'm not really sure on that.
I have only used epoxy with fiberglass to repair those plastic
motorcycle fairings. Resin didnt stick (adhere)to those things.
Is there a difference between fiberglass cloth and fiberglass rope?
You could use the the strands from the cloth your using if thats compatible with the epoxy
