So I am doing some more work at my parents house, and I noticed the front door needs a major repair. Its quite the old door, came with the house. I am not very skilled with the process, but I am a fast learner, and I can fabricate quite a lot. All around the locking mechanism which shows in the pics below, the wood has been broken due to an issue with the latch sticking and getting caught pushing and breaking both ends. I can fix the lock and such, and I could just rig that wood, I dont want to rig it though. A permanent fix would be best, so I was wondering is there a way to replace that whole vertical right side portion of wood without screwing up the door to badly? Probably not after all these years im sure those dowels and what not have set pretty well. Any response would be gratefully appreciated.
