More countersinking

Category: 3: Wings (Total 309h) — Steffen @ 21:23 — Hours: 1

I only spent an hour in the shop tonight, but I managed to get a lot done nevertheless.

First I finished countersinking the main spar bottom flanges for the skin dimples.

Then I deburred the rear spar top flanges, and dimpled them. I used my special wisegrip dimpler for these flanges, the pneumatic squeezer couldn’t reach straight on because of the angle of the flange. After dimpling, I touched up the dimples a little with my countersink. This will make the skin fit much nicer.
