There was some waviness, but not too bad. I knew that would happen so I cut it all at 1” so I could joint and plane as needed to get it to 3/4”.
The walnut was kiln dried so most of it came out stragiht. One piece warped a bit but I can straighten it when I do the glue up. The strange thing was that the offcut of the warped board did not warp, and it was thinner.
