This is an opinion: Wood is an organic material that NEVER cuts the same from stock to stock. Therefore a full depth checkering machine would become a liability instead of an asset. It is hard enough to not dig ditches with my MMC tool (after 23 years of checkering) on some stocks without NOT being able to go at it slowly down to depth.
This is fact: the only other checkering machine currently on the market is the NSK system devised and sold by J&R Engineering. The system is available in both electric motor or air powered motor. The price just went up April 1, 2012. John said so.....
