On this snowy Saturday, Sam and Teddy, along with Zaahid, went to FusionFiber to meet with Mr. Whitley for the last of their fiberglass tutorials. Here's what they brought home.
A simple ring made from one layer of 3/4 oz fiberglass mat and two layers of 1708 bi-cloth. Polyester resin was used.
A ring with balsa core! The lay-up goes like this: 1 layer 3/4 oz chop strand mat; 2 layer 1708 bi-cloth; 1 layer 1 1/2 oz chop strand mat; 1 layer 3/4" balsa core; 1 layer 1 1/2 oz chop strand mat; 1 layer 1708 bi-cloth. The result? Indestructible.
A bulkhead made by "pinching" a strip of wet fiberglass. Although the outer ring is made from fewer layers of fiberglass than the simple ring (first photo), this configuration is less flexible.
A Divinycell bulkhead. This ring was made from: 3 layers 6 oz mat; 1 layer 1708 bi-cloth. Then the Divinycell bulkhead was glassed in. This is solid enough to sit on.
