I needed to make 10'-long tent poles for our Boy Scout troop, and decided to chamfer square stock to create octagonal posts. To do this, I devised this planer jig for the job. It’s just a 2 × 4" board with a V-notch to carry the workpiece at 45° to the planer bed. I made the board a bit longer than my planer bed and screwed a stopblock to the trailing end to resist feed roller pull. Waxing the notch ensures smooth workpiece travel, and shallow kerfs at the bottom serve for dust clearance. The jig is also useful for “octoplaning” parts for all sorts of projects, including shelf clocks, trophy stands, and candlesticks.
