I started with a bit of cleanup today and then I moved on to completing the countersinking for the counter sunk screws. After setting up my microstop I completed the countersinking of the 1/8 inch center web and the single hole in the top spar cap. With all of the drilling and countersinking complete I moved on to deburring.
