Today I worked on completing the aft web tunnel assembly that I had previously started. I positioned, pilot drilled and updrilled the web to 32 and all of the angles to 30. I deburred all holes and edges to prepare for the dimpleing of the web and countersinking the angle. I need to order a 120 degree counter sink cutter to finish.
