I did a 12.5 with two motors much less powerfull than that.  I think it 
was the motor for the table top grinder some years back in S&T.  
Remember, these are geared way down.  Mine is about a 17 rpm.  Polishing 
was pretty much at the limit and icecubes to cool it down helped. ;-)    
I think the motor  I gave Bill Prewit to do his 30 inch was 1/2 hp.  I 
believe he drove the overarm with that and used a copy machine motor to 
turn the platter.  You there Bill?  I know here I can pick up surplus 
1/4 to 1/2 pretty easy.  Over that they get harder to find.
