Hello,
An adze could also be swung at angle to the axis of the log between the feet with the shoulders and stance also at an angle, from above the log, along with parallel to the length direction. In the book, De vakleu en et vak: Boederijbouw in Oost-Gelderland vanaf de eeuwwisseling tot ca,1940 Vaktermermen en werkwijze L,A. van Prooije,There are a number of personal accounts by carpenters who surfaced timbers with an adze. They also say it was one of the most difficult things to do well and only the best carpenters were good at it.
I'm just re-reading through the hewing questionnaire tab and Richard writes quite a bit on the subject. Funny enough his descriptions are the same as what I have come across in here. There's plenty of information to be found aside from physical examples that lets us know that adzing was a regular and common part of the building process, even if we can't do it.
Greetings,
Don Wagstaff
