Step 4 - BUIT 4545 PRESENTATION, Q12: INSTALLING DOOR HARDWARE

Step 4 - The first of the the video's explains the drilling of the hole for the latch.  The second video explains the process of inserting the latch into the drilled hole & marking out where the latch plate sits against the door frame so that it can be chiseled out to form a recess that the latch can sit in so it is flush with the door.  The last video looks over the chiseled out section & fixing it in.
