Default 6" Diameter Circle

I need to cut a reasonably accurate circular disk. I don't have a "fly cutter" or a bandsaw, so I was thinking that there should be some way to do this, perhaps with a jig, on the router table. Anyone have any ideas?

HI Jim

Most routers come with a edge guide that you can use for a circle cutter,most have a hole on the end for a pin/screw or can make one like below.. that's very accurate........

Jim there are some simple circle cutting jigs that can be produced in your own workshop where the circles can be cut with greater safety especially if the material you are going to cut is quite thick.
You can also make a jig from MDF and plunge rout the circle required with the use of your router and template guides.

P.S. Sorry

Jim,
This has to be the simplest circle cutting jig anyone evr saw, a strip of mdf with a hole to take a guide bush, put a pin in 6" from the edge of your cutter and fix, turn your router and plunge slowly, there you have it.

Even I can't disagree with that!

Why the surprise Derek, I'm always happy to give credit where credit is due, but when I consider that I have a better or simpler or cheaper way to carry out an operation I'm prepared to have my say, usually with photographs to make my point.

An even simpler option I've used that does not require a bushing, is to drill a hole in the router subbase to fit over a pin you put in the workpiece at the circle's center. It's a good idea to stick the work down on scrap with double sided tape.

I said it was simpler, not better.
