The notching technique is in fact faster, keep in mind these two are hewing a very large oak log here, with very big notches, and which from the sound of their axes I's guess to be extremely hard.
Oh thats funny. I watched that video and I thought gees that wood must be soft. Here is Australia we have some of the hardest woods in the world. Just down the road from me (30mins) are Yellow Box (Eucalyptus melliodora), Red Box (E. polyanthemos) Red Iron bark (E. sideroxylon) among others that have a air dried density of between 1100kg/m3(Yellow Box) to 1250kg/m3 (Grey Box/Red Iron bark). The exotic pine and cypress I can get is around 500kg/m3. Natives that I can get occasionally locally are messmate, E. obliqua (white oak equivilent?) 750kg/m3, Manna Gum, E. viminalis 650-700kg/m3 (red oak equivilent) and Blackwood and Lightwood, Acacia melanoxylon and A. implexa which my book says are around 650kg/m3 but I'm sure the stuff we have locally is much heavier/harder.
The notching did look quick but there were two of them. Is this method more than twice as fast as one person working from the top of the log?
P. radiata is the most commonly cultivated tree in the world but in its native range it is endangered.
The classic medieval (15th, 16th century) goosewing does actually look like a wing but most of the american colonial exmaples have so far changed that you really have to squint to see the resemblance if at all.
