Chances are the "d" measured flat-to-flat and not corner to corner will be no smaller than .060. With the exception of tiny 0, 1 and 2 weight rods, it's both too hard to consistently plane any tip to a d of less than .060 and almost invariably too delicate a tip to use. Whack a branch or catch a fish of any size, and all that work is shot. IIRC, the Leonard Catskill Fairy rods were also smaller, with a d somewhere around .048. But it's been a long time since I saw one of those.
Of course, d is measured on the finished hexagonal construction, so that means the sides of each triangular strip would be d/1.72, i.e., even smaller.
