I've found both the Invisidoor and Murphy door sites, and some YouTube videos. I'm kind of surprised that there are not more examples on this forum, since its a really neat idea for an HT entrance, IMO.
I've ordered the pivot hinge from Murphy door and am in the planning stage of my entrance. I should receive the hinge today, and that will allow me to finalize my plans and begin cutting. There is actually a good bit of planning and design required, especially to figure out exact pivot points, etc. I'm replacing an existing set of double doors in a 2x6 wall that need to be 'finished' on both sides. Outside 'false' bookcase, inside working door. SketchUp has been a valuable tool.
Hinges, latches, etc. are an issue. I'd like a 'tilt-a-book' latch outside and a doorknob inside. I think I know how to do this, but we'll see.
I think I'll put up a build thread so others can see what and how I did, and learn from my (inevitable) mistakes.
Wish me luck!
I'm finding that I'm smarter than I thought, but dumber than I need to be.
