anyone have any experience with fabbing a large spinner; say 16" od and 18 "
long? I haven't done it myself but I met someone who did. He made a mold or buck that he mounted in a lathe and fixed a piece of soft aluminum to it. After spinning it up he used a wooden dowel to lay the spinning metal against the form. After getting the shape he welded the hole at the nose of spinner closed and cut out the openings for the blades. Sounds pretty simple but it took him more than 6 tries to get one he kept. I understand that this is essentially the technique Cessna was using in the 1980s and at that time there was one old timer who threw all the spinners for Cessna. John Dupre' |
