had to break down a door, how to repair splintered wood around lock area?
If you're in a tight spot get the glue and a 4" X 8 " nailing plate like what is used to brace rafters. Hammer it into the side and get out the wood filler. Your glue joint will becaome the strongest area. These plates are like what is now used to reenforce the jamb around an new exterior door lock and deadbolt cutout area.
