Attachement for the XYZ machine.
I connected this spindle to my 3-Axis CNC milling machine and milled a PCB from CAD. It worked! (pictures and below)
two flanged bearings
1" aluminum shaft
15v 700ma dc power supply
This spindle was tested and cut cardboard, balsa wood, bass wood, wax, and acrylic. Next, I'm going to make a jig to attach it to my 3-axis CNC machine and mill a PCB. (Video below to see it in action)

I did an initial test machining aluminum on the lathe to make a small spindle with set screws.
