I mean, it looks like I can… but maybe one of you has been in this tarpit before and has some advice. Thanks. Jim
Thanks AG… that’s what I was looking at. I guess it a matter of how much scratchy time you want to spend converting quads. I’d 'Bay the fins but they are not available in std. tab. …I need to get up the nerve - I have the tools. Thanks again. Jim (I was unable to post a conventional reply?!)
Before I would waste a good set of fins; I’d call Rainbow or Larry at Fibberglass Fin and have a set made.
Looks like about a minute each with an air saw. If the fins aren’t available in the two tab, I wouldn’t hesitate.
Rainbow and Fiberglass fin Larry are both quality fin makers and you can’t go wrong.
I would also like to throw my own hat in the ring.
I can make custom G10 two tabbed fins in any template.
the trailing edge is the important part, (position wise).
Looks to me in above pic, the tabs won’t line up ?
Please note in the pic. It’s a bigger FCS 2 and a tiny FCS. I’ll try to find a better size match to compare in a few.
I’ve trimmed FCS fins by 1/4" so I can move fins back or forward. Sure they’re weaker, but I rarely snap them at the tabs during my powerful driving turns, lol. It’s running over drop-ins that does it.
I’d say you could go with undersized tabs if the edges don’t match perfectly.
Yorky,
In my experience, and understanding, what a fin is doing, happens around the leading edge of the fin. Therefore the distance from the tail, to the base leading edge of the fin, is the proper way to describe a fins position. If ALL fins had the same base length, then a case can be made for a trailing edge measurement to be meaningful. But, all fins don’t have the same base length, eh? Think about it.
what ever.
you know that little dot, the dot that marks where to put the fin plugs.
Well that little dot is important also.
Think about it.
… The plugs are already installed. Therefor if the back changes so does the front.
you sound like my ex.
Well, I hope your ex, left you some VAGISIL to rub all over yourself. Clearly you’re the reason she’s the ex. The other thing that is clear, is that you lack full understanding of fin design and function. You actually didn’t think about it, after all.
what gives you the right to say that about me… ? fuk u
… your just a lonley old man, so what if u went left at Sunset, or strainght at kook land. not everyone here thinks your words mean shit…
I had a logical point and you came at me, so fuck you. what you got… do you even surf any more??
keep your stupid mouth shut when it comes to anything I say, ok Billy Boy!
Your outrage is comical. Does a technical discussion of fins frighten you? Is that why you attacked me personally, and unleashed your Potty Mouth? Instead of making a run at me, you should make a run at growing up. To your ‘‘what you got?’’ question, what I’ve got is an extensive depth of experience.
If you are setting fins and marking them at the trailing edge of the fin , but know the width of the base from rear to front(4- 4 1-2") ; are you therefore not taking the front of the base into consideration??? Or am I missing something. Good to have you back around and active. Missed the Yappin’ Yorkshire! Lowel
Yes… just grind the tabs to size. I wouldn’t even worry too much if the fin outlines match perfectly, if the bases are exactly the same as the originals, or if the edges of the fin line up with the shaper’s dots. It probably doesn’t even matter too much if you have the same fin on each side.
Seriously - I recently made an asymmetrical board with fins purposefully placed in different positions, different toe and different cant when comparing one side to the other. One side was 1/2 a quad set and the other was a single keel.
The clincher? The guy, who is a goofy foot and wanted the board to be specifically for left point breaks, ended up putting a single keel in the rear plug on the quad side and rides it now as a twin keel in either direction. The whole deal just flew in the face of everything either of us expected but I trust his surfing skill and feedback as a rider.
Bottom line? Don’t sweat the details… grind those tabs and give it a try!
Leading edge does have a lot to do with how a fin performs. So does trailing edge in relation to the rail or tail…
The board in question though already has the boxes set based on the rear edges and standardish sized FCS fins.
So, like Yorky is saying, the OP would do well to make sure the trailing edges match up as closely as possible imo.
Yes you are right Yorky. Re-read your post wasn’t thinking. Plugs are installed.
Lets not destroy the poster’s thread with abuse of each other. He asked a simple question. Yes he can grind them. but how will that affect the fin’s performance in that particular board based on the placement of the plugs. have Chrisp, Rainbow or Larry grind you a set. You may wich you had those fins someday with the original base. If you were to sell them; they are worth more with original base. Peace Braddas as. Lowel
bingo we have a winner. hahaha
a over the top ego and know it all attitude.
Just like my ex.
