I’m building an exterior door jamb and door using quarter sawn sapele here in MA. The plan for the door is to use shiplapped joints between 5-6 boards to form a 39” wide door.
According to the wood EMC and dimension change coefficients, the expansion I’d have to account for is 1/16” across the entire width of my door (39” wide). But some places I read mention an expansion gap that’s nickle sized or 1/16” between each board. I’m assuming the calculator is the way to go and if so, can I install the shiplap boards tight and have the 1/16” reveals on either side of the door account for the gap?
