Potted in the 54.5, 39 and 27.25 aft ribs today. I'm getting a bit more efficient with the potting in process, so I should be done in a few more days. Then the reinforcing begins. I'm still aprehensive about the fitting of the lower skin to the lower skins, but must push forward. I feel that as long as I keep to the basics of good composite construction, even if there's a glitch, I can fix it .
