This was a lot of work and turned out nicer than I thought it would. I digitized the bathymetry lines in ArcMap and I also layed out the cribbage lines using a few GIS commands. I suppose that means that all these holes are geo-referenced. I’ve never made a cribbage board before, so I didn’t know how deep the holes should be. They cut just fine with the small down spiral bit but I didn’t set my depth deep enough so I had to use a hand drill to deepen them up. I also cut a slot in the top for the pegs and a slot in the back to hang it when not in use. Oh, by the way, the blue color is a spray tint I found at the hobby shop.
All in all, a lot of work but think the gift recipient will appreciate the fact that the holes start and end right at their lake property.
