I prepared all the main ribs for primer today. First I deburred all the matchdrilled holes, then I scrubbed all the ribs with scotch-brite. It took a while, and was nice to be done with. Can’t wait till these ribs are primed and ready to be riveted to the spars.


I decided to prepare the aileron brackets for primer too. The benchgrinder with the scotch wheel was great for smoothing the edges, then I matchdrilled them and countersunk the holes that needed that. Tomorrow will be a big priming-day!!
