Sorry for the confusion DarkSoul. When I said flatten, I meant going at it's belly with the planer to "flatten" it.
Since the passing of a relative, the garden in the backyard is starting to look pretty dismal. I don't mind if it might take a few years to mature, I've got nothing but time.
There is already some smaller bamboo growing that I use to practice arrow making with, though not very good yet. Thought I might try my hand at the bigger stuff
