Brief Description:    Final drill and countersink front spar doubler
I managed to get in a couple of hours of building after getting back from the Chino Planes of Fame airshow. I even managed to connect with a couple of people I haven't seen for a few years that I thought still had hangers at the field. There is a lot of homebuilding activity at this airport. I talked to a number of Vans builders and got some understanding from them about what's ahead in my build.

Once back home I picked up where I left off with the front spar and doubler. The doubler is clecoed into place and all holes are final drilled. I used my drill guide to help keep the holes perpendicular. I wasn't using it much earlier, but it makes sense to use it when possible. It just takes a little getting used to right technique.

There are several holes that don't see a drill yet. These holes will eventually become the attach points for the ribs. Some of the holes get a countersink and the plans want to you drill a couple of the holes with a drill press. I marked which holes were which with a lead pencil (kidding! never use a pencil on aluminum unless you want corrosion), er, Sharpie.

The countersinks are necessary in those locations because that's where the stabilizer will mate with the tailcone.
