The Guys at SOBA kindly sent me an optical center punch to try for an up and coming CNC Z Axis project.
If your not familiar with optical center punches ,think of it as a normal metal marking punch with a sniper scope attached.

Over a normal metal center punch this bit of kit may seem a bit over the top. One of the catches with making an accurate CNC machine is the fact you need another CNC machine to make it.
This is where this particular center punch will come in extremely handy why? for very accurate marking before drilling the various holes.This wont be much of a review more if an overview.
