The dadoes have to suit completely, so at all times make further elements and begin by making check cuts. Testing the dado widths and depths is fairly straightforward, as a result of many of the elements go along with lap joints. When the dados match snugly, their widths are appropriate; when the surfaces of the assembled joint are flush, the dado depths are appropriate. That’s it; you’re able to go.
