OK, technically they don't have the stiffeners riveted to them yet, but for all intents and purposes rib set #3 is complete. They turned out great. If you have a sharp eye, you might notice that the 2 lightening holes in the front of the rib are the same as the rear two. This is a slight modification on my part. The plans call for the hole to be 115mm, but I was never able to get a satisfactory flange on a hole that big. It was either off-center, or bowed the rib web until it was unusable. I'm making the remainder of the 115mm holes the same - 95mm. There will, of course be a very slight weight penalty, but I'm not installing wing lockers, so there won't be any internal bulkheads for those - probably close to an even trade.
