I set up a leveling table to try and get the shafts aligned as perfect as is possible when working with a wooden machine. The Y axis is locked down and then the leveling table is adjusted with shims and screws until the Y shafts are level in both directions. After the Y shafts were level I adjusted the Z axis shafts until they were level both directions. The Z shaft bearings were then epoxied into the oak. I am using bronze bearings on the ends of the shafts even though they don't turn. I will drill through the Oak, through the bearings and lock down the shafts with screws. |

This is the Rotozip tool I will be using in my CNC router I will probably use threaded studs and wing nuts to lock down the Rotozip. I'll add a bit of metal reinforcement across the tops of the mounts to distribute the stress of the lockdown wing nuts. |

The Z Axis slide has a groove and the tool holder has a tongue. The two pieces bolt together and the tool holder can be moved up and down about 2 inches. |
The back side of the Z Axis slide showing T-nuts for the mount bolts Update: The first piece my new machine cut was a new Z axis slide assembly. I wasn't happy with the way the one in the picture above turned out. |

The Y Axis slide I am going to program the router to cut a new Y axis assembly since the new Z assembly came out so nice on the router. |
