My father George and my nephew James came over to help out on getting all the wing ribs edge finished i.e. cleaning up all the sharp edges on the ribs and the lightening holes. They also let a hand dimpling all the wing rib holes that are hard to get at with the DRDT2 dimple press. Between the 3 of us it took 5 hours to get the entire set of nose and wing ribs cleaned up so that I could commence the fluting and flanging process.
