Shiplap and half-lap joints are created on different surfaces of a board.In this episode of 360 with 360WoodWorking the 360 guys discuss whether shiplap or half-lap joints are used for backboards.

Join the guys twice each week for six lively minutes of discussion on everything from tools to techniques to wood selection (and more). Chuck & Glen, and sometimes a surprise guest, all have their own opinions. Sometimes they agree and sometimes they don’t, but the conversation is always information packed and lots of fun.

Shiplap or Half-Lap Joints

Sometimes woodworking terms can be confusing, like shiplap and half-lap joints. In both cases 50% of the material is removed from each of the two adjoining pieces. Naturally, you might think the terms are interchangeable, but they’re not. A half-lap joint connects two pieces of wood together usually at some sort of angle (often 90°), while a shiplap joint joins the boards edge to edge. This might seem like a minor difference, but it’s as different as night and day.

  1. I made a TON of tongue and groove boards for flooring I was going to use and never did.
    I kept it and have used it for years as backs for cabinets.
    It has worked superbly and has made my projects look great.
    They fit nicely into rabbets in the back of the cabinets and I think have added structural integrity to the piece.
    Thanks fellas.

  2. Is it common to leave an oblong hole for wood movment when fastening these together across the back of a carcass?
