I got home from skydiving early today and Jackie helped me spend a few hours in the workshop to get the seat rib sub-assembly ready for priming tomorrow. It included match-drilling the two bottom skins to the rib assembly, followed by a mass exercise in deburring, edge-finishing, and dimpling.
We were just about done when the parachute club phoned to say they might need me again tomorrow, and then I remembered I had forgotten to buy more primer during the week; I'm not sure I've have enough to do the whole job now. So, in short, I'm not yet sure whether we'll be priming tomorrow or not. Hmm...
