shall this be enough?
the fin shall look like the one in the new TSJ…mr youngs blue hully looking board,
did the search but couldnt really find much
thanks a bunch…
ps my sways all screwy
Hey tjd, I haven’t made any fins before but it seems like you could always add more layers to make it more stiff. Start with an ugly prototype in the shape of the fin ('cause I’m sure the flex would be different with the template cut out and foiled than it would be with a slab of layered glass) Add layers on the prototype until you get the desired flex. Just a thought, hope it helps!
the number of layers is not as important as the sanding of the layers.
Professor Liddle My flex hero specialist sands twenty plus layers down to like five in the tip! patience and skill in tecnique
if you are boxing this fin the requirements are specific.
if you are glassing it on you can add skinny layers two or three at a time on each side seperately.
let the resin go off real good before sanding
if it doesnt you may bruise or fray the cloth making things messy in the long run.
the painstaking process of whittlin down 30 layers to five in the tip is helped along by stationing layers of different cloth periodically as markers…
seven layers in the middle, odd number so you get a center
then two different then ten on either side
when you sand you will see the telltale line
and can refrence the other siide
t oee if your foiling is true.
remember the disc is cutting flatter on one side cause you are spinning off on one trailing edge and spinning on on the other…only remedied when the grinders are made with reversable spin.
the ultimate tool for fin shaping is a rasp because it is flat
roughin out with the mini grinder is hot but the rasp will tune the mother
to stage three of the quest for perfection
there are an infinite number of steps to perfection…

more later there is a car in the yard.
I would like to recommend a Milled tooth file instead of the rasp.
30 layers? i have a waise to go…with 10 oz?
trying to rush is so i have a ribbed roller,and i will warm the resin to saturate the glass better…well i meen faster
i want to cut the template half way with a few razors then finnish with the jig saw…
all my fins i have made with three panels always seperate…/?
so the last fin i have made 1 panels no problem…
i must be srcrewing the bond…
thAts weird a car pulled up…ha
thanks for the rasp advise too im going to get a round on today
love the rasp is rad

I have clogged many milled files.
rasp to rough
rat milled to secondary sand paper to finish 36
50 80 100 220 340 440 600
three pannels fine
the outsides can be smallerplan pieces
cause you gonna shape em away anyway
you can cut the green all the way down to the glass panel
seperate lay ups disrupts the flex… and some times fails to bond strong…
,ambrose…
…hey brother Ambrose
340 440??
I d never see one of those…
what brand?
whats the w/ordry #? Idunno
I just rub em after I buy em
some times I just lose em in the sand paper pile on the shelf.sure aint 300 was that the eight hole #? at 320?
just work the progression whatever you got
stop at 150 if you like
take it to 1000 you get the gist o’ it .
never seen 500 paper either
but I’d use it
if it was there.
…ambrose…
pick nits
taste good with crow,
sorry to miss the numbers where’s my
green branch
time to strike my back.

With 10 oz volan cloth the standard is to put the wood fin in the middle, 2 layers on either side, and a glass rope bead over the leading and trailing edge.
If you want a solid volan fin my guess is about 17 layers.
I use the rule of thumb that 6 oz is 0.01 inches thick, and a fin tab is 0.350 inches thick, so you need 35 layers, or 31 if you don’t use a good roller.
For color separation you have to let the layer kick and then sand and acetone it before moving on. Use lam resin also, not sanding resin.
Bill Hickey always recommended white down the middle. Everything looks good next to white, he’d say. He would know.
Making good flex fins is tough. Learning about regular fin templates is tough, making the flex ones even tougher, because you need to learn how much flex you really want. Rainbow doesn’t gloss their flex fins b/c the gloss will crack and flake off. Instead it requires a superb polishing job.

i guess i shall answer the question …is it a fin box fin or a glass on? its a glass on is there any other …
ambrose…do you know any floor refinnishers? they have thee best paper around…ive been using this ol piece of 110 for a real long time and it cuts so nice …its purple and they through the stuff away bags of real good paper…if i can track down my flooring guy i will get u some…
you really cant beat the coke bottle green of volan it has to be one of the most beautiful colors there is…a solid volan fin really nice looking stuff…it glows in the dusk sky…
yea laminating resin sanded and acytoned…had lots for bond failers…going for the one piece…no layers
shape will be takin from nature …a buddy just got a rather large albacore tuna i told him to cut off his fins and put them on ice… i want those dimentions
Re: The Albacore, use the tail fin, lower lobe. That will have the most appropriate application to surfing.
go to the floor refinishing supplier,they have all kinds of choices!
look in the big ohone book an when you go to p-land you can go shopping for the candy sand paper!
sand paper fetish comin up!
glue down paper on dowel------new rasp tool
cheaper than metal.
one of each shape and renewable
my mind reels with the posibilities…
I use the 30 grit from conrad parducci
dennis gave me some open coat stuff I never used
I’ll bet their fine stuff is psychophine
maybe some is color coded
ooooooooooooooooooooo sand paper
my friend jesse gave me a sandpaper catalogue one time
hey how bout google sand paper?
…ambrose…
the thickness of fin panel should be 3/8" if you are going to foil it like a liddle flex fin. if you have to add some 4 oz. volan or 6.once it’s 3/8 thick, then you can start foiling away.
