By the way, question for the vets. I don't have dummy fins. I can either use FCSII fins or grab an old pair of orginal FCS fins and cut notches to make my own dummy fins. Which is the route I'll probably go. But the cant is built into the boxes. If your cut is flush, the cant is already set. Do the boxes tend to "float"in the hole? Seems unlikely as the cut is a tight fit with the jig. I guess my point is this. What's the point of dummy fins? Is it just to keep the boxes in place while the resin is curing or is it for getting the right cant? Id imagine it's the former since like i said, cant is already built into the boxes.
