My mother's 60+ year old house, in Texas, has a door frame that needs repair. The area around the lock striker plate has been enlarged over the years to accommodate several different locks and doors. How do I fill in that area so the current lock is secure? I have considered taking a piece of hardwood, trimming it to size, cutting out the place for the lock bar, and gluing the repair piece in place. I am wondering what type of glue is best for this, and if I am on the right track.
