While halfway through dimpling the stiffeners I noticed that the female die was leaving a slight mark on the inside edge of the stiffener. I posted the question on VAF whether or not I needed to replace these. The consensus was that where the marks were are not the load bearing part of the stiffener and that I needed to use a reduced diameter female die. I already have the reduced diameter dies but just didn't not think to use them. Chalk it up as another lesson learned!
Here is my airplane part christmas tree. I hung the stiffeners from the ladder and had the space heater blowing on them to help accelerate the drying since it has been so humid here.
