For interested woodworkers, here's a nice post-mortem of someone's attempt at making a Crokinole board: https://boardgamegeek.com/thread/731671/postmortem-on-the-hi... (Complete with creating a set of jigs from scratch)
Really shows how much has gone into a silly flicking game you play at the pub.
I, as a fledgling woodworker, was able to make my own board with some guidance from a friend. It's definitely a rewarding and educational project! Plus it makes a nice wall decoration when not in use. I used Purple Heart wood for the edges, which looks gorgeous but was difficult to work with. It took a few days of 3-4 hour blocks, due to a busy schedule, so a more experienced woodworker should be able to do one pretty easily.
It looks like those instructions are from 2011. CNC machines are pretty common these days and could help simplify it quite a bit.

routing or skill sawing a circle is not rocket science that requires the use of a cnc router thingie.
