Making fins

I am wanting to make some fins out of fiberglass or other materials. I have shaped fins using a bandsaw but the blade dulls quickly. any good ideas on cutting and shaping layers of fiberglass? does any one sell fin blanks that can be custom shaped? Great waves early this morning at Wrightsville! Thanks

Tepedon - re:the bandsaw blade dulling. You’re probably using the wrong blade. There are blades made specifically for cutting composite materials. Your’s is most likely a wood cutting blade. Check with any good tool supply or lumber yard - or Sears for that matter. Also check the speed of the machine-if it’s adjustable-and set it correctly for the blade you’re using. That said, the bandsaw is probably the best tool for the job. Pete
