How to repair Bedroom Door Strike Plate
This is not intended to be an ad, it's from my experience with this very problem. I used to try to hold up a small router to do this, not good for me. I've tried drilling holes and finishing up with wood chisels, this works, and as mentioned--SHARP is the key here. I now have a multi-tool, with an oscillating blade that is the trick for this. Drilling holes helps also, and then cut out the bad wood with the saw, and finish with a good SHARP chisel. I agree with cutting the replacement piece slightly larger and using a good wood glue. After the glue dries, then sand to a smooth finish, then start as if new wood altogether.
