spinner router options

[Claudio.d]

Hi everyone
i am in the process of building a small table , the cutting area is about 16 inches square the actual space is 24x24 , i am using t-slot fo the frame and the xy screw are in a sealed box with nema 23 steppers .. I managed to bolt them to my frame, I have decided to make the y axis stationary and the x axis on ball slides on a 20mm rod, i came to this decision cause of the weight factor
i plan to adapt the top portion of a lathe slide compound for the z axis
travel is about 5 inches and plan to use 2 spinners (one at the time) :a motor connented to shaft with bearings and a high speed one... with and here is my question
I came across a 30k rpm ,120v 5.3 amps surplus spinner used for scientific blending
it has a 6 mm shaft and i am looking for a small chuck for it ...any suggestions? does anyone have one?
it has a dual ac dc motor so i plan to use a speed controller on it
Thank you
Claudio
