Hi people, about to do the cavities for fin boxes but it's the first attempt so need a bit of hand-holding please :-) got the One-Pass install kit, so properly tooled up.
Got two questions:
1. I've followed the Futures youtube tutorial, used the shims and the Timmy tool to get the height of the jig plate correct and made the cavity on a scrap piece of foam. I'm not sure how deep the fin box is supposed to sink but this looks to me like the cavity might be a bit shallow. The shallower part of the cavity is barely 1mm deep. The router bit has been pushed up against the nut of the router as per instructions. I should disclose at this point that the router I'm using is a Katsu 101748 which as far as I understand is a carbon copy of the Makita 0701 (0700 in the US).
2. The Futures tutorial for the One-Pass indicates that "when alligning the left fin, use the right hash marks on the target" and vice versa. (tutorial link: https://youtu.be/Qq3CXyGOoLY?list=FL_k-G2HuSxGfnNV8kRe0KGA and the target hash mark instruction is at 2:40). Is the 'hash mark' as per photo? And if so why use this instead of the middle?
Cheers :-)
