Working Mahogany ATM, and its crappy stuff, not at all well seasoned. Shipped in Saran Wrap, 11.25" wide when unwrapped, but 2 weeks in my heated garage and its shrunk to 11 3/16" and some boards 41" long have winded 4" in 3 weeks. Difficult to get them flattened out enough to fit a breadboard end, but once its fitted, the pressure should unwind them eventually. It worked well for the first one, but I had much better wood then, well seasoned.
So I'm having a heck of a time getting breadboard ends fitted to the chest lids. Blanket chest, Dec 2014 issue of Fine WoodWorking, but I am adding an aromatic eastern red cedar lining. My question is, in 20" of biscuit jointed Mahogany width, how much seasonal movement should I allow for? The code I have now to carve the screw holes and the pockets for the ebony covers, allows for a total of .6" at the ends of the breadboards. .3" each side assuming the center 2 screws and a spline are the only place it will be glued. Std procedure IOW. Is that excessive? Its 22 minutes run time per breadboard stick on my mill. Mostly by brute force, using a subroutine to do the center pair of holes, but the outer 4 of the 6 are going to be done by a step & repeat of the whole subroutine at 25 thou intervals in order to get the movement room.
