Knock-Down Cutting Support Grid — board plan

What to buy, and which parts come off which board.

Cuts are listed longest-first, which is how they should be made: the awkward pieces get placed while there is still board to place them on. The layout assumes one end of each board is squared off (1") and that every cut costs 1/8" of kerf — the reason six 16″ parts do not fit on a 96″ board.
