Tom - Always loved the animations on Marc's old site, and have long wondered why he took them down, they really are a powerful description of the system. Was not aware of his new site, both glad they're back, and that you posted the link
Nic – I would remind you that the same two reasons that probably drove people to hew timber to rectilinear still and will always apply, Wood is far harder to join in the round, (more time consuming in every way, from handling – a major challenge to dog off well enough to scribe with out danger of movement during layup – way more expensive to cut, perhaps only twofold plus after you build the skills ) and sap wood is quick to rot. In the grand scheme, when you count everything (fuel for saws and the folks who drive them, and all those extra days commuting, there is no impact advantage) I know of no good book explaining how to join round work, which, ironically, makes it not so different from any other system of layout
French Scribe is really a system for joining sawn timber, though the basic precepts of how layout and layups are approached can be borrowed to join round work.
Only the tool ( and I say this being one who prefers the plumbette to the bubble, hands down ) used to convey information from one stick to another is different.
Planes of reference are the same, notice the datums in these views. Of course, it took extra time to snap them accurately.
Shoulders are the time eater, much to “cope” with.
Don't mean to say too much nay, it's big fun to do, the sense of accomplishment runs high when it's done. Much of that, having to do with the challenge it holds.
Sawn natural curves hold nine tenths of the organic appeal and the efficiency factor is way higher.
