It's the pad that insures good contact of the tape with the head over all the 
tracks.  The roller is just a revolving pressure pad and the better it 
drives, the better the machine will sound.  Grinding the rollers can only improve 
things.

Don't know!  The rollers in the Chamby 300 we have are indentical to our 
rollers and at 3/8" wide they will certainly suit 1/2" tape even after grinding.  
Remember, when we grind we reduce the surface area of the roller by 1/3rd yet 
standard tape drive is improved because you are concentrating the drive area.
