I made this baseplate a few years ago based on plans from a book on routers either by Patrick Spellman or Bill Hylton. It consisits of two bronze bushings with an i.d. to match the bolts. The bolts need to be directly in line with the centerl of the bit and an equal distance from the same.

I haven't figured out how to post more than one attachment at a time. Here is it in use. Each bushing rides on opposite sides and automatically centers on the workpiece.
