The drawings show different dimmensions for the oc spacing of the hole in the brackets. It states that this will be the case in the plans, but the drawings seem backwards from what is intuitive to me.
Spacing from the Spar Web to the center hinge point of 310 is 1 1/4". Spacing from the Spar Reinforcment(VS-307) to the center of 309 is 1 3/8.
Obviously, the hole centers will not line up even close.
The leading edge of the rudder will taper some, making some sense as it narrows at the top that you would want to suck that in, but then the Rudder spar is not parallel to the VS and the hinges would most certainly bind. I would think that having the VS Spar and the Rudder Spar parallel makes the most sense.
I am thinking that 310 hinge line needs to center at 1 7/16 to match up with 309. The Skin then gets tapered, per the plans, 1/8" more overhang on the top. I think the skin taper is probably optional and wont make much of a difference if at all in appearance, but it is easily done.
Anyway, I am going to proceed with making the hinge center spacing match and be parallel to the spar unless I hear otherwise from one of you.
