[Lab] ideas for small spindle for small cnc

Yes, I ordered a flex shaft for a dremel, three different small chuck
systems to try with other motors and one model airplane motor (with speed
control and a servo tester to act as the speed interface).

It's not for metal, it's for portable balsa cutting. I'm making a dedicated
portable machine for that.

I'm also making a generic portable machine which I will use for general
purpose. Sign making, plastics, engraving, wood, or whatever I'm in the mood

I think a dremel flex shaft would be good for balsa cutting.  If you remove
the cap on the end, the thread could be used to mount it to the machine.
You then have all of the dremel collets available for bit holding.  This
would probably work for engraving too.  I doubt it would be rigid enough for
any metal work, but you might be able to cut some plastics or do pcb milling
with it too.
