Re: Cutting out glassed instructures
There is one fact you can count on that will make this job easier than you think; the wood is not touching the fiberglass. There is a gap in between them. Using this fact, don’t feel compelled to cut very close to the hull. You can cut a 1/8 or ? of an inch away from the hull (using a Fiberglass cutting blade on a reciprocating saw) or a cutting disc on an angel grinder. After the wood is separated, you can fair the extra FB using a flap disk. Personally I liked the use of the cutting disk as the space and angel permits. It is easy to cut a line on different distances from the hull and see if I am still cutting through the wood or I hit the gap. The disk is also much cheaper the blade which tends to bend very quickly. I limited my reciprocating saw use to those tight corners that I couldn’t reach with my cutting disk. It will get much easier when you get the hang of it.
