How to Build a Storage Chest

Apply wood glue to the edges where the boards meet, using your 1x4 spacer to realign them as you go. Partially tighten two bar clamps on each assembly, and wipe away excess glue with a wet rag. Use a scrap block and a hammer to level uneven seams, as shown, before further tightening the clamps. Add a third bar clamp on the opposite side of each assembly to prevent it from cupping. Build the lid the same way, using four 1x6s flush at the ends. Remove the clamps after one hour, and allow the glue to cure overnight.
