Thickness planers are awesome. But I don't have one.
They're an expensive and specialized piece of equipment. A new one starts around $300, and the price just goes up from there. I'd like one, sure, but most of my woodworking projects don’t require it, so I haven’t made the investment yet. There are a few other tools I'm more interested in before I make the leap to a planer.
But there are times when I have a rough piece of wood that needs to be trimmed down to a consistent thikness or large course areas need to be smoothed out. Instead of picking up my orbital sander and going to town for 45 minutes to thickness the piece of wood, I turned to my table saw. While this trick is limited to wood with a width of approximately 6 inches, it can save you a ton of time for small projects. It's a really simple process.
