Features to Look For in a Box Joint Jig

  • Adjustability: The more you can fine‑tune finger width and spacing, the more versatile your jig.
  • Indexing Accuracy: Positive stops or indexing bars make repeat cuts consistent.
  • Fence Stability: A sturdy fence prevents chatter and keeps cuts square.
  • Compatibility: Ensure the jig fits your table saw’s miter slots (standard 3/4″ wide is most common).

Tips for Using Your Finger Joint Jig

  • Test on Scrap: Before cutting your project parts, make test cuts on scrap wood to dial in spacing and depth.
  • Use a Dedicated Blade: A box joint or dado blade set will give cleaner, tighter fitting fingers.
  • Add Featherboards: Hold stock tight to the fence during multiple passes to improve surface quality and safety.
  • Verify Fit: After cutting one side, dry‑fit the mating piece to ensure fingers align cleanly before glue‑up.
