It was a very quick night of building. I just had to dimple the interior holes on the vertical stabilizer skin that I couldn't reach with the squeezer. It seems like every time I do this, I forget the way to setup the c-frame... I started with the male dimple die on the bottom and then was trying to move the die into the hole (blindly as it was below the skin) without scratching up the skin, while also holding the folded skin open wide enough to fit the c-frame inside, while holding down the skin to the dimple die, while whacking the top die in the c-frame with a hammer. Needless to say, I didn't have enough hands for that so I stopped being stupid, thought about it for four seconds, and remembered it's much easier to put the male die in the top piece, then the skin just hangs down naturally and there is no struggle for space inside the folded skin as the hammer/whacking business happens outside -- no wrestling required.
After finishing the skin dimpling, the instructions say to dimple the rear spar and countersink the doubler to accept the dimpled spar so that the assembly sits flush against the last fuselage bulkhead (detailed here with the dashed rounded-rectangle in the plans).
I still don't have the VS-410, 411, and 412 brackets so I haven't match drilled the holes yet and I don't want to dimple/countersink the spar and doubler as that will make it difficult to get accurate holes in the brackets.
I still haven't primed any parts... If I continue on, the next step is to start on the rudder. We'll see if I get priming sorted out or if keep burying my head in the sand...
