Hi Ron and welcome. You may be able to find a universal one that will fit. Lee Valley sells one that I think Milescraft makes.
Thanks, I found one from Peachtree. Was hoping to get one that didn't require me to drill holes, but that seems unlikely. Wanted to keep a constant, accurate radius.Jasper tools makes universal bases...
Wish I'd have seen this before ordering the other...oh well...I started with this router table kit...from Lee Valley tools...
