      I am actually interested in all construction techniques and materials. I have the Bingham book on
      interlibrary loan request, and I will buy it if it proves out. After perusing the block article in
      the Bigham book, I will think about design and materials and get back with the group. I just did a
      search of the Woodenboat index and there were several articles. If anybody else has any plans or
      design info I could look at, I would be very interested.

      John, I couldn't make the link work.

        Harry,
        One more resource - "The Rigger's Apprentice" by Brion Toss has a small
        section on rope-stropped blocks. Some recommendations on sheave sizes and a
        couple of simple diagrams on fiddle shapes and sizes. It will also teach
        you how to do the rope work. Probably not worth buying the book for just
        the block info but the it's a great resource for traditional rigging.
        Larry
