I’m building a door. I find that mortises (my frame is mortise and tenon, the tenons were easy on a table saw) are much harder to create if you don’t have a proper plunge router. I’m using some chisels and it works fine but I have eight mortises to make and I’ve finished 1.5 in about the same number of hours. I don’t want to buy a plunge router, because I’m unemployed at the moment, but it would finish the job in minutes. I guess I’ll go get to chiseling! Next door I make will use half laps, so I can use the table saw for both ends of the joinery.
