With all the housing dadoes completed and the main body together, we must cut the middle shelf to length and determine the shoulder lines for the stepped part of the stepped housing dado joint. The practicalities ensure that all of the shoulder lines close up perfectly. The patterns we use are important to a wide range of other projects, so learning them now aids us in establishing patterns of construction. These joints are used in a wide range of shelving units, ranging from bookshelves to toy storage and many other projects. The unit we build here has three types of commonly used housing dado, and the joints we consider mostly as the bookshelf joints. That said, it can be used for toy boxes and firewood boxes, but we also use it in drawer making too.
