A friend and I were discussing ways to drill cribbage board holes with
reasonable accuracy, and this is what I came up with. Remembering that
there was some discussion about this on the wreck, I thought I'd post
it here.

In case it isn't self explanatory, here are a few salient points.

This will only work for holes that go all the way through, though it's
not difficult to imagine building it to allow the board to be
underneath the jig,

The large top piece is the jig itself, and the 6 pieces below it
represent the board, moved along for each hole to be drilled.

The jig should be clamped to the drill press table, and should have a
fence to set the position of the line of holes.

The first hole is drilled wherever you want to start, and the next 4
are drilled by using a pin through hole 'b' and the previous board
hole.

The 6th hole is positioned by putting the pin through hole 'a' and the
first hole drilled in the board. All subsequent holes in the line are
positioned using hole 'a', ensuring proper spacing for both individual
holes and hole groups.

Any and all critiques are welcome.
