Plans are made to be broken. I had planned to use four boards for the back panel of the Dutch tool chest, but when I realized that with some careful dimensioning I could use three, I went for it. I had planned to use tongue-and-groove, but when I tried it on a scrap piece my 1/4” tongue looked so small and flimsy on my 15/16” boards that I went with ship-lapped panels with a 1/2” rabbet and a 1/4” bead. I only used glue on 1/3 of the width of each board to allow for wood movement and used spacers to leave about 1/8” gap between the boards. I will nail the back and front to the carcass, but am thinking of doing that after painting the chest. #DutchToolChest #ToolChest #HandToolsOnly #Poplar #Woodworking
