Sure, I will try to remember when I get home. The hole was from an old door handle set that I removed. It was the size of a quarter or so. You can't get any better than a dutchman, Silva style: [this video]

I'm replacing Mortise locks with contemporary levers on solid wood doors in my apartment. The doors are pine, 1 3/4" thick. I've removed the Mortise locks, leaving behind two large holes and the Mortise cut-out in the door (first photo). My goal is to stain the doors, so I want to patch the entire area and avoid using fillers for a nice, clean look; I believe this type of patch is called a Dutchman Patch [this video] (second photo). I purchased a low-end plunge router [LINK] to cut out the area, but I'm not exactly sure what size bit is suitable to cut 1/2" deep; the area is about 4" x 7".

I came across a This Old House video [this video] that demonstrates how to fill a mortise lock with a Dutchman. The video patches one side of the door. I want to patch both sides so I can drill it out and replace it with a modern door lever. In the video, I believe they are repairing a previous patch so they can reinstall a mortise lock. Because I want to fill the cavity, should I simply cut each side deeper and at different sizes so the smaller insert uses the larger insert for glue backing? What's the preferred method for completely filling the mortise with new wood?
