While cruising around buying wood for making some cutting boards, I have run across a number of cutting board kits and I just don't get it and wonder just what I am missing.
The way I have always calculated a board foot is cubic inches divided 144 (1 1/4 x 12 x 18 = 270ci and that is around a 2bf board) One particular kit I saw ended at that size but said the kit was 4.5-5bf.
Obviously there is waste but not 60%, I expect more like a half a bf. These are end cut and are checkered maple & (PH or Walnut)
What am I missing?
