Fixing a cracked "fin hole"

General Discussion
1

I don’t know how to fix the hole that the screw goes through in the back of my fin. What is this term anyways?

What’s the best way to redeem this fin, if any?  Help!  I have ding repair materials to begin with.

Thanks brudda.  Chris

I'd grind the side of the fin in that area away until you grind into the side of the hole. then build up the part that you grinded away with layer after layer of cloth. once done, fill in the hole with resin, and re drill a new hole. check to make sure  it fits in the box, if too loose, build back up again, if too tight, grind back down to size. this is just what I'd do, but someone else may have a better solution.

Have you made the fix yet?

no:  haven’t even got the fin yet… why, Bill?   Did fix a couple dings in my bomb today… fun.

Just a curious mind, that wants to know.

I like the idea of cyano for it’s fluidity… getting into all the fibers of a cracked fin lamination…

however, I like the idea of the viscosity of resin and the case that it is resin that built the fin lamination in the first place… and it’s the same stuff it’s made of…

so… I’m undecided on how to fix…other than the fact that i have resin and don’t have cyano at this point in time… probably will go with my UV resin…

 

your thoughts?

How about grind a little of the fin to create a longer tab.  Cut the old tab at the old screw hole.  re-drill a new hole a little further along.

Hey Grace1

The Universal Fin Tab was created exactly for your problem.

Thanks Brian:  This looks possible for me… do you have a larger photo of this onesheet?  I can’t see anything on it to know if I want to buy… pretty cheap price, any distributors in Cali?  Somewhere I could pick up one in Ventura.?  Just wondering.

Hey Grace1

I’ve attached a pdf of the instruction sheet I made for clarity. We’re the only supplier of these fin tabs as far as I know.

Let me know if you have any questions

Well, I used some ‘super glue’ (cyanoacrylate) and clamped to fix. Thanks for everyones help.
