1. Orbital Sander 2. Planer 3. Jigsaw 4. Drill with wire brush attachment
I started by planing down the edges in random spots, then did the same along the flat surfaces. The goal is to make the wood look worn and uneven by getting rid of the straight, smooth lines
After recreating the look of saw marks, etching grooves and lines using a jigsaw it is time for sanding to level out the roughness. An orbital sander makes fast work of this.
Here's the key to make it look authentic: use a drill with wire attachment to cut tiny grooves into the wood, opening up the grain.
