scale model "revolver" window flange arrived today- Using the cut off base of a scuba tank I will make a fixture to test it to repeated cycles to 2000 feet, and if the plastic viewport shows no crazing, make a jig to drill out 12 holes in each flange on the sub, increasing visibilty out of each window by about %50 and reducing the conning tower weight by over 140 pounds
