Making a 16 mm wooden board from a log using hand axes

Bare hands are too soft to make a wooden chest. But metal, fire and nature can be turned into tools given time and skills. With the help of a human being the tools made in previous videos had no problem cutting a tree down but that is a gross activity. I want to experience how a tree turns into a 16 mm flat and straight wooden board and I want to know what that feels like in my body. I am no wood worker but I am curious, and I am set on making a fully functional wooden tool chest, even if I did not have a single hand tool to begin with. And a wooden chest is made out of a wooden board and this is how it came to be.
I made a beam using a different technique in my previous video about tool maintenance. The method used here was a lot quicker and I think I am starting to get a hold of the hewing technique when done with an axe like this. The two main differences between my two attempts are that in this video I do not split of the side but also that I later cut the beam in two before slitting it. One out of the four short boards cracked in this video which is better than the three from my first attempt, trying to split the long first beam (of screen) so this is only the successful attempt. In the background you can see the first attempts ending up in a lot shorter/longer and only one usable full size board.
The egg always has to precede the chicken just like a tool box being nothing but a box if it had no tools.
