Title: Can't align it even with the cone
Review: The objective of the subbase is to be able to use template guides that are centered around the bit. The problem with this subbase is that Bosch, in saving a few sheckels, chose to have it cast out of high impact plastic. Unfortunately, the result is that there is 1/32" camber in the base. Consequently when you mount it, it's not flat, it doesn't hold the guide template in the proper relationshiip with the base, and even the most minor adjustments to the height of the bit result in a misalignment of the bit to the template guide. I purchased the centering cone, but it had no effect on the usefulness of this base. Since you have to remove the motor in order to get the centering cone out (there isn't enough clearance, as there would be with a normal router), everything gets misaligned and you're better off moving the base around until you get it aligned manually. I wish Bosch would have made the base out of phenolic and machined it rather than having it cast.
