True, but I'm not sure if I could grind them as flat and true as I'd like. I suppose I could pick up a cheap spare and try it out.
I watched a master machinist grind a shim once. He used wet/dry sandpaper and worked the shim in a figure "8" pattern. He said that the figure 8 pattern kept the grind level since the changes of direction leveled the pressure on all sides. I've tried it since and it works................................DJ
