I spent most of the day working on the porch door today. I hollowed-out the opening for the mortice lock (which took a long time), fit the handle, plates/etc. I also installed the strike plate in the jamb (it turned out really well), then I installed the stop moulding, caulked it, and gave it a coat of paint.
Right now I did the caulking around the door panels, putty-filled some old nail holes, and I'm waiting for this to dry. Once that's done, I can start working on the window for it.
