This log is 3 years old, very gnarly and hard, but beautifully complex inside so well worth resharpening the chain a few times!
I start off by using the vertical milling attachment to take off one side to even it up.
Next I clamp the chainsaw in the horizontal Alaskan Mill attachment and slice the planks off one by one. note I have previously cut a flat horizontal face on top of the log to make this possible.
