Quartersawing on a Wood-Mizer
I do a bit of quarter sawing with high-grade white oak logs on a Wood-Mizer (hydraulic) bandsaw. I prefer to start with an octagon, making all slab cuts parallel to the pith. This ensures that the pith will be parallel to the saw bed at all times. The critical thing is to produce enough flat surfaces so that each quarter can easily be turned and clamped. This method produces boards with parallel sides, which I find easier to edge and to stack. Below are some illustrations of the method I use.

Why not buy backing boards from a veneer mill? They are perfectly quarter sawn and of high grade.
From the original questioner:
The guy I'm sawing for wants this, and I'm just trying to accommodate him. He has to have this green, I think.
The Wood-Mizer handbook describes a method of modified quarter sawing that is very easy to do and which provides a good amount of true quartered from the right logs. I find it works with larger logs. The log is positioned with the best possible face up and the levelers are used to center the pith (that is, the center of the log is brought to the same height on both ends). Roughly the top third of the log is severed and put aside. Flip and remove the other third and set aside. Set the center third on its side and box out the heart, leaving two pieces that will provide true quartered boards, and one center cant. The outside thirds are placed on the mill on edge giving boards that range from flat through rift, then quartered and back through rift to flat. Waste is minimized and edging is easier, since most of the flitches have one flat edge.
