The plywood template is at the bottom right. The shaft was rotated 15 degrees and another wire was shaped and brazed in place. Smaller wire was later added so that the openings in the wire mesh were less a inch. The finished wire form was 45 inches in diameter. After the wire form was covered with fiberglass and finshed the inner part of the wires to the far end of the shaft were cut and removed. This left a 15 inch diameter opening at the bottom of the top terminal. The shaft was unscrewed and removed from the inside and outside of the terminal.
