Today, I didn’t make it outside until late, so I didn’t get a lot of work done. Here’s me starting on deburring the skin. Yes, I am using the Van’s recommended “spin a drill bit in your fingers” method. It works for me.
Action shot of me deburring.
An example of a deburred hole. The hole on the right is deburred. There is a very small chamfer on it from the oversized drill bit. It’s easier to see because it’s catching the light from above.
Deburred hole there on the right.
After deburring, I scuffed up the interior of the skin with a maroon scotchbrite pad.
Scuffed, ready to dimple.
Because it was so late, I didn’t want to break out the c-frame. I grabbed the hand squeezer and finished what I could reach.
These are regular (not "tank") dimples. No circles when you use the blue tape trick.
And here’s the vertical stabilizer skin, deburred and dimpled around the perimeter. When sound level permits, I’ll get the c-frame out and dimple the remaining holes.
Almost done with the skin.
I counted 104 holes per side for deburring. That’s 208 holes, 416 deburring operations needed. I usually spin the bit 4 times, which makes 1664 spins of the drill bit. Oww…
1.0 hour closer to being done.
