Can anyone provide height and width dimension of the base on a mini tutle fin ?
Need to determine if they can be cut down to fit a US Box

Cheers

Kev

@ Sheer Tip, thanks for the images but thats a standard tuttle box not a mini tuttle.

@ Mark, cheers mate, thoughts it could be done but don't have a set of mini tuttles in front of me to look at and eyeball for size.
Plan is to make a jig off standard us box side fins for a quad set up and then cut down the mini turtles to suit.
Pin in the back and then cut out the lug at front and drill hole...

Cheers

Yeah that is what I am doing as the MT base is only about 15mm deep and a US or slot is 25mm. So you can take thickness otu of the base (down to 9mm) no probs but it is still not deep enough so moulding a whole new head is preferable.

I used silicone 2K to mould off a US fin and it works well to convert a MT to slot or US.

ooops, I missed the 'Mini' bit in the subject AND the question

^^ I'd take the boards back and demand refund
the whole idea is that it is an interference fit - so if you take the bolts out the fin is jammed so tight it will stay in (for a while anyway as flexing when sailing loosens it of course)
Thus, the FIN head is supposed to be a tiny bit too large and sanded a TINY bit to fit... IF need be. Maybe 30% of fins need a light sand.

A box in a board that is too big is an obvious stuff-up.
A fin that is a ****teenth too big is not.




(As an aside, mini tuttle makes more sense as the angle on the sides is more extreme - if the fin box is too wide, or too long, there is more chance of the sides or the ends "jamming up" as you tighten the screw.... lees turns to effect the same interference fit ..... so less likely to need sanding IMHO
