[Lab] Coaxial shafts...

I want to independently rotate two or possibly three arms - like the hands
of a clock - and am looking for a "shaft within a shaft within a shaft"
assembly. Each arms is to be separately controlled by 360 degree servos (not
continuous rotation) or steppers. Right now, I am looking to see what's
available and so far I've drawn a blank.
To your response, the Dremel only provides one shaft and I'm looking for
more. As for bearings, it would be a ball race or just cold-metal (brass on
brass). I am still looking for possible ideas.

But what are the dimensions and what speeds and torques ??
Could you use flex drives such as For Dremel of Canadian Tire have a
cheepie for $3.00 If You use these one must be sure to turn such that
the inner cable is tightened not unwound.
Last alternative is to build your own when the question becomes:::
what of the inside bearing betweent the inner and outer shafts ?

I'm looking for a supplier of clock-like concentric shaft assemblies to use
for a large art display.
Ideally, I'm looking for two independent shafts (one inside the other) on a
common axis to convey two rotary motions from one side of a baffle to the
Hope that you get what I'm after.
Any ideas please?
