Drilling the rear spar flange strips

I have have been working on the rear spar, getting the flange strips cut and drilled and making the rear spar attach doubler. I fabricated the aileron bracket doublers and have etched, alodined and painted all these pieces. I have to paint the rear spar with some epoxy paint which I will this weekend. Once this is done and dried, I will rivet on all the pieces. I can then move on to the ribs and start deburring all the edges and lighting holes then flute the ribs to get them straight. I will then start attaching the ribs to the spars on the bench before I mount the whole thing in the jig and prepare for drilling on wing skins. One thing to note about the rear spar is that it's has a Z bend in it. However there are two different angles on the bend. One goes on the top and the other on the bottom. You reverse them to make a right hand/left hand spar. You have to stop and think about that before you make two left hand spars. Van's gets calls all the time about guys making two of the same part. Airplanes are symetrical so you have left and right parts.
