I hope to build a super router table one of these days with a router
lift, nice fence, drawers, etc. Until then I have my no frills Bosch I
bought at Home Depot for approximately $200.

Now I want to buy new mounting plate. Unfortunately, the router plate
seems to be a size not sold anywhe 11.5 inches by a 9 1/16 inches.
Do I have to make my own? How dumb is that?

Maybe it's time for me to start the super router table after all...heck
I've got a dozen bookmarks of great homemeade tables that would blow
the bits out of the one I have now...
