The next thing that I did tonight was match drill the inboard aileron attach brackets to the wings. The plans indicate one of these holes gets a flush rivet and the others universal rivets. Since there wasn't enough room for the microstop countersink, I used the hand deburring tool with the countersink bit and did these by hand. Once everything was match drilled and countersunk, I deburred all of the holes in the aileron attach brackets.
