A plunge router would be the easiest way to get the outside ring nice and clean.

This seams like a terrible idea.

I have seen several ash trays on fire in the summer time on construction sites. When they set in the sun and a few butts are in their. They go up in smoke. Literally.

I think a router will do it. You might chisels as well.

If time wasn't an issue, you could also use LT's to do it. LT=Liberal Termites. They just go in circles, don't get much accomplished and show up for free food.

A router. Easy to do. You can pick one up at a pawn shop for a good price.

I saw a cutter attachment for 4-1/2 inch grinders. It's a disc 4 inch or so diameter with chain saw teeth around it. The use it for carving totems, etc.

Yes, a router would be the quick way. You could drill a series of holes and then use a chisel and gouge to finish it. The most appropriate way, considering the forum, would be to use gouges and chisels. You would learn to use tools that will always be available and you could even start by making the tools yourself.

The skills you learn last a lifetime and you would be teaching them to the next generation.

I could do that in less than 1 second...a little bit of detonating cord goes a long way.

Yah, but you'd use a ton or glue putting it back together and another ton of sand paper finishing it. Speed is not always what it's cracked up to be. I learned that from my first girl friend.

There is no problem, big or small, that cannot be resolved with the proper application of high explosives.

If you split the log you did something wrong. I have watched trees brought down with three wraps of det cord.

I also got to watch, at close quarters, an acre of area cleared to 10 inches deep in hard pan. You didn't hear a sound, see any dust you just felt a "thump" that was like a hit in your feet but really dull. Walked over and sunk in the now powdered hard pan. The area was being turned into a parking lot and the excavator was having an impossible time getting through the hard pan. That man was an artist with explosives.
