Hi 14'ers!
I've been fluting the forward ribs based on the "tabletop" then "straight edge" approaches, and I think I'm getting good results. However the ribs with a cutout for the stiffeners exhibit something I'm unsure of.
You can see from the difference in image 1 and 2 below that the aft upper portion of the rib seem to "cog" between these two orientations. It doesn't take much force to alight the fore and aft sections into a line, but the rib really doesn't want to sit that way by itself.
The fluting activity doesn't make this tendency better, in fact it probably worsens it a bit. But as you can sorta see from the edge shot below, I'm getting the rivet holes lined up nicely.
So am I ok, or missing something?
TY!
