Ed,
	Like you, I remove the bare minimum of wood, leaving a trace of the 
grooves. But I also take care to remove enough wood from the middle of the 
bridge so that there is a flat surface between front and back, and use a 
straight edge to see that this is the case. I'm thinking maybe I don't need 
to be _quite_ so meticulous about that, assuming adequate bearing. We're 
talking thousandths of an inch here (1 to 5, say), nothing dramatic.
