I had planned to do the priming, but it wasn't to be.
It is taking a significant amount of time to finish off the prep on all of the wing skins. It took a further 3 hours today to finish prepping two of the big (bottom) wing skins. Finally all 6 main skins, and all of the smaller wingtip components were ready for priming.
One of the wing skins needed three holes to be dimpled. The plans call for dimpling in two places, but it's actually three holes. One other wing skin needed a hole enlarged to 3/8 so that the tie-down is accessible. Once again I needed a drill I didn't have. But I knew this was coming so I had previously gone to Screwfix and purchased a comprehensive set of engineering drills - £45 or so. This allowed me to incrementally enlarge the hole two drill sizes at a time. Maybe the Unibit would have been quicker, but the result looks ok.
Another 3 hours today went in deoxidining all of the prepared parts. Because little "working" of the parts had been necessary (although it didn't feel like it from the time I spent prepping these parts), there weren't too many fingerprints etc, so I could maybe have got away without doing this. A major difficulty was washing off the deoxidine afterwards. The panels are large and unwieldy. I had to take them outside the workshop to hose them down. It was raining intermittently, and gusty. A gust of wind could have been enough to put a permanent bend in a wing skin. My feeling is every time you handle one of these parts you risk damage. Plan to move them as little as possible!
The remaining couple of hours was taken up with setting up the large paint booth and organising everything for the spray job. There's absolutely no free space in the workshop at present so every job takes longer than it would otherwise. I had to figure out where to lay out the unpainted skins, where to put them when they were being sprayed, and where to stack them afterwards. There was only space in the paint booth for two of these activities.
