Perhaps drill a small hole into the fin (where it snapped), then glue a thin metal bar in there. After that you could wrap some tape around the metal bar to pad it out and stop it wiggling.

That's one kind of easy solution I can think of. Hardest bit would be finding the right bit of metal, but I think you could use a nail or a screw with the head cut off or something.

... man,,,, save your time and effort, get these ones,,, they perform great and better than the original fins in my opinion!

Its possible. But is it worth while?

You could fix it easily as described above. But it's just a cheapsh.i.t fin supplied by the manufacturer. They break and the performance is pretty crap. There's a whole world of really good fins out there. Go shopping.

I want to fix it because I've knocked like 5+ fins out, there no wind this week so I have time to tinker around to make it work lol.

I'll give it a go fixing and see how it goes, I'll post a pick once it's done.

Make up a copy of your fin box in a block of timber with a router, drill a hole into damaged fin and score to form a key, put into jig and pour in a suitable compound( epoxy, araldyte etc, when set remove, sand back and shape, you'll need a solution in the jig for an easy release of fin when set

ok then.

Make a stew of epoxy and cut up carbon. build up the base with that.
Then grind back 1/2"mm on either side 40mm up the fin base lay up up 2 strips of carbon fibre.
Then drill the hole back out.
That will make it stronger than before.

Best scenario for sure, but is it worth it?

Hi
been doing this kind of stuff for years and to be honest most times u buy another product
to fix something ,and your time its often cheaper to go and buy another one.
Look online for a special.

So I used araldite and a dremel to fix it, just put a bit of metal 2-3cms down and then added araldite around it. I then used a dremel to take off excess glue and shape the end, fits fine and feels solid. Took around 5-10mins to get it the right shape.

Bike shops sell kits to remake tabs for fairings... A mold you can shape and some sort of epoxy to fill it with. Now I've typed all that out, I'm sure what you've done works just as well and is cheaper
