When you consider the slab sawn middle cuts of the tree, there are differences between say the 2 or 3 VERY middle ones and one on either side of those, where the grain starts to curve around. Some people refer to those areas as 3/4 sawn. The first one shown is not quite there IMO. But actual technical description may even vary by geographical region of the country. I just stated what we say around my part of the country, yet the whole post was about the fiddleback to start with. When you get down to it, slab sawing messes up as many stocks as it lays out right, which is why I never used the method. I always went for layout, and any waste was too bad since I was concentrating on gunstocks and not lumber...Steve
