2.5hrs
Made the form and cutting blocks for the wing root ribs and ground out the fluting grooves in it and the nose rib blocks I had forgot to grind them into.
The root ribs top flange goes from 60° at the nose to 90° at the rear spar. I puzzled over best way to do that and decided to just make the forms like all the others and free handedly not beat it down all the way at the front. As easy as cutting out and bending is once the forms are made, I can try a couple if I mess up one or two, and I only need a good left and a good right, so not worth trying to overthink the formers..... We will see
Total time spent building: 47 hours
Total Cost: $8276
Airplane + consumables + project specific costs: $5340
Tools, etc.. I will keep for future projects: $2936
