Circle cutting router jigs

Hey Blue

You can check out my blog on making circular dished trays with a router and jig.

All you would have to do is adjust the size of the jig to your own dimensions and use the jig to cut your blank to the correct diameter. This method is deadly accurate and I have used the jig for a variety of applications since I made my own jig.

Good Luck

Narm had a show that included making a band saw jig to cut circles with there’s a tape/DVD about it, it’s a very handy jig.
It’s in this jig show: DVD &/or Measured Drawing Item #0101.

Here’s another way I use this method a lot.

Great ideas, and thank you! Now, do you use a plunge router to start the cut or how do you start cuts without the bit being in contact with the work? I saw in the video from Trev (hadn’t seen that particular jig before) that it looked like the router is started and then moved into contact with the workpiece before the first rotation is started, was that right? What about with the jig you use, Jim?

You got it correct Blue.

The depth is set on the router. You then bring the router bit into the blank, holding the router against the clamped stop, then spin the wood blank around the entire circumference. Re-adjust depth of router and repeat, until the blank is cut across the entire depth desired.

I like Grumpy’s jig as well. It would take less manufacturing than the jig I used. since I have not used that one, I am not sure which one would be more accurate.
