I am about to install a maple shiplap back on a chest of drawers and need some advice on the gap width for expansion. Each of four maple boards are approximately 36 x 5. Any help would be appreciated.

2.5mm assuming hard maple; less (say 2 mm) for soft maple.

Google says a nickel is 1.95mm thick and I'm to lazy to go out to the shop and confirm with my calipers. OP, make sure that's a new nickel your using, I'd hate for the gap to me .02mm less using a worn nickel.

One of the many problems ancient Rome had was citizens shaving flakes of gold from their gold coins. Led to inflation.
