Tongue & Dado Joinery

When building a case, you want the joinery to be both strong and easy to make. Tongue and dado joinery is a good example with a few advantages. The interlocking parts make aligning the case pieces during assembly a snap. And it provides a good amount of glue surface for a long-lasting connection. Another benefit of this joint is that, with a few adjustments, it works equally well on both cases and drawers.
