10" tall and pretty thin walls (1/4 to 3/8" at the bottom) for me.
Lots of storms this spring/summer. This sycamore (what this hollow form is on) fell across our road and in the culvert. Most of it is still in the creek. It will take a larger tractor than mine to get out. I did grab a branch to play with. I needed windshield wipers for my face shield it was so wet. Boy did it cut nice and easy. I was also trying out my new Trend Bosch (3/4") Stabilizer. Wow that is a game changer!
