When creating a checkerboard blank for a segmented pen, it is important to drill the hole for the brass tubes exactly in the middle. I use a brad-tip bit to drill the hole, so, before gluing four pieces of wood together to make the checkerboard blank, I use a block plane to shave off a very very tiny splinter of wood on the one corner of all four pieces of wood that will be at the center of the blank. This gives the brad tip a channel to guide it straight down the center of the blank without wandering.
I hope someone finds that useful :0)
