Most of the time the fence is in place in case it snags. And it has a few times. That's more of a problem on the large drill press. On this little one it is so under powered. If it catches, it will just stall.

I will probably look at doing some milling of aluminum angle and square on the KRMx02 or CNC Construction Set. You can plasma cut aluminum, but the finish wont be as good. For plasma, I only need to support the part by one end. For milling both ends will need to be supported.

The key to the new Z axis is the improved X carriage. I started with a 1000mm rail and cut it in half. 5-1/4" of the rail support is removed from each half. This allows me to create a simpler motor and bearing mount system.
