As hard as we try to raise our kids right and steer them onto the straight and narrow, the inevitable finally happened and my daughter fell into the wrong crowd: cribbage players. After hanging out with these hooligans for a few years, she’s begun an attempt to pull me into this shady underworld. She’s asked if I can make her a cribbage board. That’s how it starts, and before you know it you’re at a friends house borrowing his cnc metal lathe to spin down your own pegs.
It seemed to me the biggest problem with building a cribbage board was indexing the drill. A fifty dollar template didn’t seem like the right answer either, so this is what I came up with. It’s very similar to my box joint jig – just a box in a box with a 3’ threaded rod run through all 4 sides. There is a nut epoxied into one side of the inside box, and I just used double nuts and washers on the outside edges to hold it with respect to the outside frame. 16tpi rod gives me a quarter inch spacing with 4 cranks, and 1/2 in between the runs with 8 cranks. Those were the counts I used for the test piece. To get the second row I just put a shim against the indexing strip and dialed it back to the start.
I thought I would add toggles to hold it in place, but just holding itagainst the stops with my left hand while cranking and drilling with my right worked just fine. The only irregularities were due to the crappiness of my press and the hard maple making the bit wander. The “extra” hole, well, let’s just say there’s some danger in repetitive motion exercises.
