Stopped by the hangar for just half an hour to make progress on the kit. Ended up drilling one Horizontal Stabalizer Stiffener with #30 drill bit. Moved the cleco's and continued to drill until complete. Then enlarged the 8th hole on each side to #21 in accordance with manual.
Drilled vertically with Spar slightly off the workbench, but after thinking about it drilling horizontal would make more sense and provide more lateral support for Spar.
