A couple of clarifications.
The 0.7086 higher than a std tuttle, is that measured perpendicular to the root of the fin or perpendicular to the top surface?
radius on the corners between the sides and the front/back edges?
Any idea on the proper drilling for the barrel nuts or will that depend on whether you're using std or metric?
I can't seem to get the Deep Tuttle dimension from the back to the first bolt hole to work out (you said 0.491, I get 0.514). Are the holes in a different location than the std Tuttle box?
Thanks for the Great Reply Roger!!
