Future C-5 Installation

Anyone have experience installing the Future C-5 fins? I just picked up a set and the fin box is unique and therefore requires its own jig, which costs in the neighborhood of $80. Any way to get around using the $80 jig for these fins and still get good results? I don’t do enough C-5 boards to justify the cost.

Thanks in advance.

just mark it on the blank and freehand route it. Works for me…

regards,

Håvard
