Just so you know, bearings will slightly mar the work. One trick that prevents marring and wear to the tips of brass fingers is to use cardboard, like the kind used for cereal boxes. Cut a strip, fit it between the work and the fingers and clamp the cardboard to the steady rest. Make sure the tips of the fingers are in full contact with the cardboard and then put oil between the work and cardboard. I have turned finished aluminum at 2800 rpm with no significant wear to the work, fingers or cardboard ... and the work was solidly supported. Might give it a try.
