We have this door in our bathroom that is for a closet/medicine cabinet/laundry shoot. The thing is 7' high and rounded. I designed this bathroom many years ago and I don't like straight walls, doors or women. So the door weighs about 150lbs, give or take 100lbs. The outside of it is white laminate.
A few months ago the cabinet hinges started to croak as the door is very heavy. It also has shelves built into it which I think my wife stores bowling balls or rocks on. The hinges gradually sagged to where it was hitting the bottom of the cabinet and wouldn't close all the way.
I found four hinges in my workshop that were the same design, from the same manufacturer but these were much larger and I figured I would install them. (I could build a Space Shuttle with the stuff in my workshop, a really small cheap Space Shuttle.)
I remove one of the center hinges and try to fit in the larger hinge which fits into the hole in the door, but the holes in the back end of course don't line up because these are larger but being smart, I had a drill with me. I drill the holes in the cabinet to match the hinge and install the thing.
Now I try to close the door, but being this hinge is much larger, the door won't close because it has a larger swing so I have change all the hinges. No problem (I built many cabinets so this is simple)
I get my drill, screw drivers, pliers, screws and anything else I may need because after I start this, I can't let go of the door because if at least two of the hinges are not on, the door will crash on the floor breaking off a large piece of it. And this door probably cost $1,000.00 today. (about the same as a two gallon Nano tank) It would be real hard to duplicate being it is round.
The bathroom floor of course is tile, 12" white, very slippery tiles. So I take a kitchen chair which has wooden legs and bring it into the bathroom. A ladder wouldn't fit in there so I need the chair to stand on.
I gently remove the top hinge while I am holding the weight of the door with my right arm. Now I take the new hinge and stick it in and drill the holes with my bad arm (I had a shoulder operation and it is not 100% yet but good enough for this simple job)
I have to hold the hinge, drill the holes, put in the screw and screw it in, all with my left hand, and this has to be done with the door almost closed, so I have to reach about 3' in to the dark closet while I am on the chair holding the weight of the door. I can barely reach it. No problem.
As I push the drill to make the hole, the chair slips backward on the tiles forcing me to grab the shelf. The shelf with all the hardware on it. Most of the hardware bounces into the laundry shoot at the bottom of the cabinet. Luckily, I was still holding the weight of the door and the bowling balls, or barbells so it didn't break.
But now, I can't close the door so it is hanging on the bottom hinges, I can't get down because the chair is to far back and even though I am jumping to edge it closer, it keeps moving backward. I have no screws to temporarily secure the door and I have to pee.
Luckily for me, I also brought a tool with me that would allow me to remedy this situation, my cell phone. So I call my neighbor. His wife is my fish sitter so they know how to get into my house. Ring......Ring.....Ring....Ring...."The person you have called is not available". (Of course not)
OK, so I call his wife. Ring...Ring...Ring...She is also not available. Like Duh
So I gradually start inching down as I use my fingers to "walk" up the door and hold it's weight. This is when I realized I should have removed the bowling balls from the shelves.
I am almost down and my fingers are aching from the weight when my phone rings. It's my neighbor. I tell him real fast, "get over here".
He finds his wife who knows how to get in my house and comes over just in time to give me this horrified look and take the weight off the door.
Now with someone holding the weight, it is a snap.
The large spring near the top hinge is to "help" take the weight of the rocks and other heavy things my wife feels is necessary to store on a cabinet door.
