Hello folks, I am trying to explore possible variations in the design and production of T6 / SNJ / Harvard engine cowlings and in particular the internal radius from the outside face of the prop shaft to the inside edge of the cowl nose. Could I ask those of you with an NAA aircraft in the hangar to take two simple measurements for me and post them, and the aircrafts ID and model in this thread? I am after two measurements (1 each side of the prop shaft to allow for a cowl that is sitting offset), and to measure in inches down to 1/8" or better the distance from the face of the prop shaft to the inside radius lip of the cowl nose, ideally horizontally from the prop and in both directions. ie I am trying to measure the size of the "hole" smiles The two measurements, allowing for a standard diameter of the prop shaft, will then give me the diameter of the internal opening of the cowl, and I am keen to see if this is standardised across the NAA family or if it varies from factory or model? I am expecting it to be uniform between the T6 and SNJ but I am not so sure about a Canadian Harvard etc Any assistance would be greatly appreciated. Regards Mark Pilkington |
