I am making a kitchen benchtop of blackwood on a ply base. Did not have enough thick planks to do the whole thing of solid wood. I will screw it from below and will cut slots in the ply rather than holes to allow for some movement
The tangential shrinkage of blackwood is listed as 4%. This would make a rather alarming 14 mm over a 350 mm width.
However this appears to mean over full range from green timber with 30% moisture to completely dry.
Does anyone have a feel for how much swelling/shrinkage I should allow for? The timber is air dried in my shed, daily relative humidity ranging from about 50% to 95% going by the Met Bureau figues.
