    • Recommended Uses: Furniture construction, frame assembly, and other projects requiring sturdy joinery.
  4. Dowel Joint:
    • Strengths: Provides alignment during assembly, moderate strength.
    • Weaknesses: Relies heavily on glue strength, may weaken over time.
    • Recommended Uses: Cabinetmaking, frame assembly, and other projects where alignment is critical.
  5. Miter Joint:
    • Strengths: Creates clean, seamless corners with no visible end grain.
    • Weaknesses: Weak without reinforcement, requires precise cutting.
