a lot of time but it didnt cost much, sofar. I think about $30 in paint and glue. Most of the material is scrap wood cans and aluminium flashing and wires of all sorts of guage. The PH is a piece of PVC sewerpipe( had to have sewerpipe just because Im a sewerpipe sailor ) The pushrods for the dive planes are s/s bicycle spokes, as well as the prop shafts, which are housed in s/s brake lines and packed with petrolium grease and capped with 1/4" brass pipe compression fittings for packing the shaft holes to the PH. I will be posting the progress as the serious detailing begins. First I must finish sheeting the hull which has come to a slowdown, because mos of the sheets will have to be cut odd shapes , water holes cut and then the piece bent and shaped to fit. Then the entire hull will be glazed with autobody putty and sections sanded to give it the stressed metal look. The weld seams will be added last before primer. Then the fun begins
