Have you done much chainsaw work? Because to "gouge a big hole" is
definitely NOT something easily done with a chainsaw, ESPECIALLY in a
stump. If it was that easy, he'd just cut up the stump in little
pieces and put them out with the trash, why bother with the hole. The
OP seems well aware of the problems of chain sawing a stump.

It's also REALLY dangerous because to do a hole you're going to be using
the tip which you aren't supposed to do. Unless you enjoy chainsaws
bouncing into your face that is.
