Prepare all R915 Stiffeners for cutting. I made a jig from scrap to insure that all stiffeners would be uniform in shape. I used 3M Clear PP2500 Transparency Film to make lots of small tags to identify parts. Marking tags with part numbers using a Sharpie Super Permanent Marker. I punched a hole in each tag tying each to parts with very thin phenolic coated magnet wire... hoping to withstand the Alumiprep and Alodine baths.
