Reclaimed wood rarely arrives square. Joint edges with a hand plane or sanding block, then scribe to fit irregular walls. Use story sticks for repeatable measurements. Cut away oil-soaked sections, and avoid painted surfaces that chip. Mark defects you plan to celebrate versus those demanding reinforcement. Preparation transforms unpredictable boards into precise components that welcome precise assembly.
Glue and screws cover most needs. Add pocket holes for hidden strength, or threaded inserts for removable posts. Through-bolts with washers stabilize tall trees against wracking. Corner blocks tame wobbles in thrifted stools. Where vibration matters, combine wood glue with construction adhesive. Remember to pilot and countersink, preventing splits and leaving paws safe from protruding metal.
