2006-08-22 Started working on the Main spar today. First I taped the gap closed between the spar web and the doubler.
2006-08-22 Had to attach platenuts to the spar and as always step one is to open up the holes to the correct size: IE:Drill.
2006-08-22 Step two is to deburr the holes.
2006-08-22 and step three is to dimple, but the spar is too thick for that so, the dimple step becomes a countersink step.
