I love Steve Bachus’ video. He makes a great bear, and it sells, and it doesn’t take any wood at all. It’s a pretty good starting point if you’re not sure you really want to get into this life.
For most people, the bear comes out pretty small. It’s proportional in the slipcase picture, but Steve’s a big guy. What I mean to say is, it will be tricky with a big-box, “regular” chainsaw. You’ll find the bear a lot easier to carve with a shortish (12″ or even 8″) bar and a dime or quarter tip. As always when running a chainsaw, wear your chaps.
