📚 Understanding Dado Widths

A dado is a rectangular groove cut across the grain. The width should match your material thickness with appropriate clearance.

📐 Fit Types

  • Tight Fit: For solid wood, subtract 1/32" for a snug fit
  • Loose Fit: For plywood, add 1/32" for seasonal movement
  • Labyrinth: Alternate dados for stronger joints

💡 Pro Tips

  • Test fit with scrap material first
  • Account for wood movement in wide pieces
  • Use a dedicated dado blade for best results
  • Stacked dado blades give cleaner walls than wobble
