[Abhimanyu Kumar] is renovating a hotel in Nainital, near the India-Nepal border, and like any self-respecting Lord of the Rings fan, he wanted to give the restaurant a Hobbit theme. He built circular windows and to top it off a gorgeous round door complete with dragon hinges.
I asked him how well the doors work, as the 50kg (over 110lbs) weight of each of the doors must put a lot of strain on the hinges. [Abhimanyu] told me, “The door opens quite smoothly.While building the hinges even I was concerned about needing support as all other commercially available hinges we tried broke down or got bent.”
However, once the dragon hinge was installed it worked better that we expected and the door stays about 0.5″ over the ground at all times. The dragon hinges (made from 1/4-inch iron) integrate the hinge pins to the wings of the dragon, making it look like they are taking off when the doors open.
He has posted plenty of pictures of the build and the final product looks incredible. The tail of the dragon is quite long and provides a lot of support for the entire door. Each hinge itself weighs about 30kg, so it should be strong enough to hold up a door for a long time without any sagging. Kudos to him for some serious engineering!
