Lathes are for people who can't cut circles by hand

So Mr Chickadee wants to make a treadle lathe, and starts by cutting a perfect wheel out of some boards using just a handsaw and drawknife... I'm guessing the lathe is going to be a present for one of his friends who can't cut perfect circles with a saw cause he clearly has no need for a lathe. His joinery is also freaking amazing, from 9:30 through to 10:00 he demonstrates tongue-and-groove planes (I never knew these actually existed before tonight). In fact I'm wondering if this is really a trailer for an action movie in which the bad guys choose the the wrong woodworker to pick on.
