DH77K: Cut a Doorway
In most houses I cut doorways into an addition after the house is assembled and during addition construction - then I do all the cutting from the outside.
But in the DH77K as well as customizations that add a door onto a porch or other places the floor sticks out past the wall, it is difficult to use a straight edge to guide the first cut. In these cases I most often cut the door before assembly, and that is what I am doing in this slideshow.
