Holy goban, my first attempt at creating a go game board, drilling holes
A few years ago, I went on creating heavy playing boards for the go game, actually made half a dozen of them.
In a previous post, I describe how I took large chunk of wood, turned them in thick boards and made custom tools to draw the grid, ie lines & hoshis.
My first experiments were a little more hackish, since go stones were not easy to find, I used black and white marbles, that needed holes to stand still on board.
Too bad marbles aren't as easy to play as flat stones, tss.
