Too late, already made 4 ribs... wish I had done that.  I'll just have to make adjustment to the nose and spar height as I go.  I would hope Leonard would make the correction for future builders!
One deviation from the plans USUALLY results in 10 more later.  You only have time invested in 4 ribs and a rib jig.  Buy the accurate drawing from Leonard for $10.

Aww... I taped all my pages together, did my best to lines up the lines, and verified cord length. Now you're telling me I gotta get all scientific? Boo!

Ribs are Formers. The spars carry the load. Build ribs to fit the Spars.
Good judgment comes from experience, and a lot of that comes from bad judgment.

And build them all to the same outline, whatever that may be. That's the critical part along with matching the spars.....

If money is spent for plans, then more money should NOT have to be spent for ACCURATE plans.  Just the way I see it. But then again that is what I do. Make accurate plans.
