It looks like Larry told the walnut that he delivered that us NYers were hoighty toighty folks and that the walnut should bow to me once I went to go use it.
My boards are about 9" wide, and I'm using a 6" jointer, so I have the guard off and am using the old flip it around technique. The jointer is set to a very light pass - about half a mm (I can read that scale better than the English today). Given this light pass, is it normal for many, many passes to be needed? I am jointing so that the bow points upward - I'm not removing any material on the middle of the board yet.
The bow was slight. The walnut arrived face planed, so I cut down to approximate length, jointed an edge on each board and laid the pieces out to see if I was gonna be lucky. The boards agreed for about 2/3 the length, but then diverged to be maybe 2 - 3 mm apart from each other at the other ends.
I guess I'm just experiencing a moment of low confidence and want to make sure I'm not going to end up with a piece of veneer for a tabletop while I take a short break and drink some fluids.
Just remembered a question - other than hearing the jointer remove material across the whole board, how do I know my board face is flat?
