I see all of these good recommendations of circle cutting jigs for portable routers, but, can anyone recommend jigs for router tables? I need to make a number of uniformly-sized wheels that have been roughly sized (witha circle cutting jig) on a bandsaw and thought a similar setup would apply to a router table. Would need to know which direction the blank should rotate; location of where the bit should be cutting into the blank; angle of the jig relative to the bit.

If you need to make a bunch of the same size, you could make a template out if thin 1/4" material- using any of the jigs listed above (mine is a simple piece of scrap 1/2" thick plywood 6"x24" with a carriage bolt in one end and the router mounted to the other- The carriage bolt goes through the middle of the circle and I adjust the diameter by moving the carriage bolt closer or father away from the router).

once you have your template, rough cut all your circles with band/jig saw keeping 1/16 to 1/8 wide of the desired circle, mount the template to it with double sided tape (you need less than you think- very sticky stuff) and use a flush trim bearing guided bit and you'll have identical, perfect circles every time without having to drill a hole in the middle.

It's a bit of a process, but if you need a bunch, once the template is set it's smooth sailing... plus it's nice not putting a hole in the middle...
