Trying to mate this Z fin with a Carbon Art. It’s a very tight fit and takes a fair bit of wiggling to get it to where it is in the pic. I can get the front of the tuttle head to sit flush with the board but not the rear. Have trawled through the subject on here and other forums. Am I correct in thinking that I just need to sand the front and rear surfaces for it to fit flush?

Ok thanks Elmo. How do I work out which area to sand once I’ve done that?

Agree with last two. But always test if you can get it to sit with front flush or rear flush but never both. Then you know it’s just too long or deep but the tapers are correct

if it will only ever sit with one end flush but never the other no matter what you do it’s gonna be way harder.

so are you sure u can’t make it sit the other way?
