Hi, folks
I've got an ancient door that I'd like to use in a project, but it's not flat: When I close it, the bottom reaches the door frame about an inch and a half before the top of the door.
This door is simply four tongue-and-groove boards that are held together with two cross pieces -- on at the top and one at the bottom. It's about 32 inches wide and 6'4" tall. Unlike modern doors, this one is only about an inch thick. It was used as an exterior cellar door on our 1816 Pennsylvania farmhouse when we took possession. Now, I plan on using it as an interior door on the kids' new basement playroom.
What's the best way to flatten this thing out?
Thanks!
Mark
