[ATM] RE: mirror grinding

Damn.... it seems that a brake rotor would be a very nice tool, indeed; 
easy to hold on to, and the mass of it would help do the work.  Also, 
wouldn't the "porosity" in the cast iron help hold onto the grit?  Great 
idea if it would work; and since an "end cap" (closure) for an iron pipe 
will work, I don't see why a rotor wouldn't work. Possibly the only 
difference being the rotor being softer (Rockwell)........
