BobL....what kind of wood is that?

It's called Marri, it's a type of bloodwood. It comes with varying amounts of resinous streaks.
From stuff lie this which also has some nice fiddle happening as well

I can see some use for curved material. I liked the curved bench he had at the very end. It seemed as if the video was a rushed thing. He didn't even have the saws fueled up. All in all it looked pretty straight forward.

What kind of mill is that? Looked pretty ridgid.

Nice find, peterrum. I wish they had shown how they make the first curved cut. They are definitely pulling/pushing hard to make that cut, but it doesn't seem to bog the saws. They must be cutting with both the bottom and top of the bar since they're making a flat bar cut a curve. I'll be the saw kerf is twice what it would be cutting flat.

I actively search out curved logs but cut them perpendicular to the curve, like BobL has done. Concave curves are easy - there's 2 in every crotch. Good convex curves are not that common. This shelf was made from oak. I had to take off the sapwood with a drawknife - it doesn't take long for sapwood to rot and get infected with bugs around here.

The great thing about CSM is that it lets you use the unique features that nature gives you.

One of the pictures on the site shows a peice of aluminum or something flexed down the curve to make the first cut.
