264721 <gtgrouch@r...> 2018‑01‑12 Re: Which way does crotch wood move
If the grain swirls about a center - the branch collar of the crotch limb - that
center will move in and out. If you still have enough wood to determine which
side was the inside, it will cup away from that, just like flat-sawn wood.
Again, each piece is unique. You might best determine movement by leaving it on
a flat surface after freshly cut.

I've found those sections with burned grain to be fairly stable.

Hope this helps, I don't feel like I'm explaining it very well.

Indeed.  Of course, in this case I already have the cut wood, but that is
how it was cut.  But how does it move?

With crotch wood, you have to examine each piece. But a general rule of
thumb is to cut slabs from the trunk perpendicular to the branch.

Friends:

I have a fair amount of walnut crotch wood, cut from a tree on my mother's
land years ago.  There are two forms:  the real exotic flamey kind with
grain in all directions, and the ones cut from near the split that are
partial ellipses.  I am trying to design using both.  SO, does anybody know
how the grain expands and contracts in crotch-wood:

a) the flame kind;
b) in the ellipses that sort of look like they are flatsawn but with the
grain following the elliptical shape and a lot of reversals and exotic
touches?

Cheers!
