Ribs

I had a board made with a center line down the middle for laying out the wing rib jig. At first I thought that the center line dims for the spars were 31" apart. This is not the case on my template. It is more like 30 3/16". The reason why I am doing this jig instead of finishing the fuse side is so I can make sure my spars will be in the right place for there fittings. The fuse side dims do not add up right so I am doing some double checking. Anyway it is something I will not have to do later and I can do this part at my house.
