I'm about to drill the forward longeron/stiffener to match the rudder pedal bushing blocks. I looked at Dan C's site, and I like the way he did it (marking the stiffener and then removing it and drilling on the bench), so I'll probably do that, but I have a question about the lateral positioning of the blocks...
As you move aft along the stiffener, the distance between the stiffeners (and the skin) gets greater due to the curvature/angle of the fuselage as a whole. So do you drill such that the distance between the *blocks* is constant (which would successively reduce the edge distance on the stiffener), or do you drill such that blocks are always in the same position on each stiffener (which I would think would allow the rudder pedals to "slop" side-to-side once installed in an aft location)?
I think the first is the case, but then...
