Stack your lumber with 1/2"-thick strips of scrap lumber between each piece, then direct air flow over the pile. If you can set things up in a heated space, drying time is surprisingly quick. I've had micro lumber drop from 25% moisture content to 10% (and ready to build with) in less than a month.Web

The main difference between a drill press and a mill is the axes of cutting movement and accuracy. Milling machines have at least 3 axes of movement (X, Y & Z) and are much more precise. Drill presses are used to drill vertical (Z-axis) holes in workpieces. Here, the cutting tool only makes contact with the workpiece on its tip.Web
