I like Bauer's idea.

You can just start at the outside with the router and work your way to the center. However, as you get deeper, you have trouble with getting the router close to the outside. You'd essentially have a little ledge every time you reached the maximum bit depth.

But that's the inside of the planter, so maybe not so bad?

Or maybe a ship auger bit? Or a six inch regular bit? On a circle jig?

Maybe this drill bit? I thought you could use a regular drill on a circle jig, drill a few shallow passes. Then move the drill in, cut another circle, etc.. Then just bust out what's in between.

No matter what you plan on doing, if you're going to use power tools, be sure to have somebody start recording with their phone, have a beer before you start, and don't forget to say, "hey y'all, watch this!"
