This fellow demonstrates a way to hew with a regular felling axe. The way he marks the line with the chalk line is classic and applies for pretty much ny use of the tool. The cuts he makes vertically leave what are called juggles, they are cut in to maybe 3/4 inch from the marked line.
When he starts cutting off the juggles with the felling axe is where he breaks from hewing as I know and practice it - but he demonstrates that it can be done and it can work.
This fellow is doing it a bit more the way I learned, with standing on the log to cut the juggles and working the tool vertically, not horizontally, throughout the process. He also uses the felling axe to knock off the juggles, then switches to a lighter hewing axe to bring it to the line and get the cleanest possible face.
A heavier hewing axe, mine weighs in around eleven pounds, is good for blowing off the juggles in short order, and can then be used to do the finish work as well. I choke up quite a bit for doing the closer, finishing cuts.
There's an immense amount of information to be learned from YouTube, from how to hew logs, to how to put them together into buildings. Well worth spending some time browsing.
Oh, the heavy axe - it takes some time to get used to working with it, but you don't swing it like a felling axe, and you let the weight work for you. It is work, and it takes strength, but you might notice that the guys in the second
video are not youngsters. Neither am I. Never worked with a hewing axe until I was in my mid-fifties, and I ride a desk for a living
