Scott I have all of your plane books . Excellent reading. I made my first japanese plane from osage orange about 10 yrs ago its off 5 deg from 1/4 sawn. No splits yet. Tnx for posting all these great videos !!
Thanks, I'm glad you enjoy the books and I hope they've been a help. Osage orange would be interesting to try as a plane body and it's good to know you've had good experience with it. I'll have to try and get a hold of some.
Really good question. I'm afraid I'll have to bow to my teachers and predecessors on this as both Japanese and Western planes have the grain oriented bark side down to the work, and when I've asked and done research on why I find the arguments not totally convincing. With the grain of the dai oriented down to the work, when the dai eventually cups cross its width the edges of the plane must be brought into line rather than the center portion along its length. This -perhaps- makes it a little easier to flatten the sole. Also, with a quartersawn orientation, the wedging action of the blade is along grain lines; while this might not result in immediate failure, I suspect the life of such a dai is often shorter than the flatsawn orientation. It might also affect the grip on the blade. Regardless, Japanese masters are adamant on this point (as are their Western counterparts) so suspect there is a subtle but important difference that has been observed over the near millennium they have been using these planes. But I'll keep trying to get an answer that satisfies me.

Did you hang your Daruma? How is it secured without a wedge? Thank you very much for making and posting these videos.
Why don't you use quarter sawn?
