I finally had the chance to complete the ribs. Most of the time was taken with accurately measuring for the tube fit and as you can see from the one wing installation I think I have it right. There are also aligned holes in all the ribs to feed the gear and aileron extensions or fit a guide tube if I want.

I also added enough with the doubler to prevent the joiner from busting through if pushed too hard when the wings are installed. This was a constant problem with the original soft balsa rib and doubler.

There is a lot more skin to remove and fine tuning all the ribs and edges before fabbing new skins. Still have not firmed up the decision, but the area ahead of the wheel pockets will likely remain. The conformal curves were a pain to shape and bond on and with the additional structure I do not believe there will be any compromise. I also have to decide if the current bond for the ribs to the spars will be adequate or if additional structure will need to be added. The shear webs alone may be enough.

On that note the lower spar will get C/F tape before the skin is installed. As with the Harvard I want to ensure proper washout is maintained when the skins are applied and that will require fabbing fixtures or figuring out some method to fasten each to my Adjusto-Jig.
