I'm designing a small spice rack to go next to our stove. It'll be made from sapele that I'm planning to mill to a ~1/2 thickness. The shelves will span a 22-1/2" area, will be 3" wide and the spices are mostly very light weight in plastic jars. I'll also have a strip of 1/8" x 1/8" maple on the shelf lip as a stop so the jars won't fall off and the back butts up against a wall. We run the vent any time we're using the stove so not sure how much moisture would play a role here. Based on the design I'd hate to have to add shelf bracing to the back.
Question
Do you foresee risk of the shelf from 1/2" thick sapele bowing across a 22-1/2 span with this little bit of weight ?
