Tie-down bars & Rear spar prep

Hours: 5.7 | Posted in Spars & Skeleton

Fabricated and drilled the tie-down bars to the front spars.  Drilled & attached the nutplates for the aileron bellcrank brackets.  I used a short bolt stacked with washers to hold a nutplate in place as a jig for drilling.  The bars are off to await priming, which I intend to do as a batch with the rear spar components; they also need to be tapped for the 3/8 bolt threads.

Prepped the rear spar components: drilled, deburred, countersunk and dimpled as appropriate (above the doubler at the inboard end, since these dimples would be nearly impossible once the doublers are riveted in place; their thickness prevents access with the dimple dies).  I need to order some more primer and scotchbrite to move forward on these; now there’s nothing to do besides start prepping wing ribs.
