Bang-up job on the Antic Vulture! You also debunked one of the great myths of Proctor kits - that they are difficult and tedious. As you said they are actually well designed and the hand machined pieces fit with uncanny precision. I notice your cap-strips were hardwood and wingtips were laminations. The newer stuff is balsa and bamboo respectively. Not being the patient type I skipped the Ducco cement and nails method of rib capping for the method in the photo below. It allows you to pick up the assmbly in the jaws of the "clamp" and glue both sides. A shot of accelerator and viola, insta-rib!
