I’ve given up on using deburring tools on the skins.  If I use it enough to remove the bur, I have the beginnings of a countersink, and that’s bad. There are too many stories of over-deburred holes on the internets.   I’m not going to be one of them.

I can deburr with nothing other than a maroon scotchbrite pad without enlarging the holes at all.  The only downside is no polished aluminum on the exterior.

The angle drill came in today.  Having a real angle drill with various extensions and various length bits is absolutely worth it.  It’s so much better than the angle drill attachment that we borrowed.  I had no trouble drilling the remaining holes necessary.  Lots of unclecoing followed.

Next up: deburr all those freshly drilled holes, dimple the skins, countersink the spars and then put it back together and rivet!

Berck: 2 hours, Jonah: 1 hour.
