Started work on Practice Kit part 2. Cut and trimmed the stiffeners. Used snips to get close, then band sander and finally scotchbrite wheel. Screwed up one stiffener-rivet hole is too close to edge. If this was on the aircraft, would have to order another one. But, this is practice—hope to get some of the screwups out of the way before I begin with the real stuff. 1.5hrs.
