How would you go about cutting a notch in a regular 2x4 stud across the grain, so that the notch is 1.5" into the grain and 3.5" along it? (i.e. to embed one 2x4 crosswise into another).
I guess a jigsaw could be used but it seems that there's got to be a better way. What tool should be used to make this cut?
