Countersinking wedge, proseal aileron
I bought a new drill press tonight, put it together and continued countersinking the wedges. I have about 1/2 a flap wedge to do and I'll be done. I found a pretty good method of countersinking the opposite side. The first side is easy to countersink without chatter, but the other side you have to support the pilot. Basically I took a short piece of wedge, taped it to my level, drill a #40 hole in it. Then I lay the wedge I want to countersink on it, opposing the angles so it sits flat. The I set on the drill press and drill away.

I also prosealed up one of the aileron wedges and cleco'd it to the table. Takes about 3 days to setup enough where I can rivet it. I'm limited on space right now, so I can only do one at a time.
