Over the weekend Menards had 1 by's on sale. So I bought a 1X10 to make 2 deeps. Boxes came out really well. Finger joints were tight. Not bad for not having a dado blade. Very slow though! I didn't think about it till done that a 1X10 is only 9-1/2 inches. My frames still are above the bottom. Should have i bought 1X12's?
