Sometimes we have to make rabbets which do not run throughout the piece: they stop more or less close to one of its ends.
The Stanley 78 is a metal rabbet plane with adjustable side fence; it is able to mount the blade in a further position as well as in the standard way. This setting (bullnose) allows you to work close to obstacles, for example near stiles and rails intersection or in the case of a blind rabbet. However, even though the plane works in bullnose configuration, the short sole needs a void space for a correct job.
For this purpose a mortice can be cut at blind rabbet extremity by using a saw and a mortice chisel.
A scrap piece can be clamped for adsorbing the plane shots and avoiding the damage of the blind edge.
