Oh My God how boring is this?!!! Two hours in and I've got the spacers, ribs, brackets and bottom skin all deburred and edge-finished and ready for priming. Top skin and spar to go... ...aaand, another hour of effort and we're done! All these bits are now ready for cleaning and priming. If the weather is bad enough that I don't go skydiving, but good enough for spraying then I'll see if I can get them done this weekend...
