    Greetings!

    I'm going to be getting some Rohacell 31, 1mm thickness. Anybody interested in a group buy?

    Alternately, I'm looking for a reliable and reputable supplier of small sizes ; and/or lower cost than ~$125/m^2 ; and/or suitable alternatives.

    What are you planning on making with 1 mm rohacell core? Really thin and light fins?

    Why not skip the fiber glass core? Once CF applied it will be fairly stiff.

    I did a set of fins with 1/16 balsa core with a layer of cf on each side. Worked well.

    Fiberglass core is simply to know exactly where the midline is.

    And yes, some cf-foam-cf ought to do very well as-is.

    Be advised, I don't have any high expectations or theories going in. I just think it ought to make some very nice fins :-D
