Door, noun:

A movable barrier of wood or other material, usually turning on hinges or sliding in a groove, and serving to close or open a passage into a building or room.

That which the dog is always on the wrong side

—Oxford English Dictionary, mostly.

Dedicated to my children, Josephine and Isaac, for no particular reason other than that I love them very much, perhaps with the hope that they will eventually stop slamming the front door. That door that I made, you know. That’s really nice. And shouldn’t be slammed so hard. Not while I’m in earshot anyway.

Safety Tip

Have you read those endless pages of safety warnings that come with every new power tool? You know, the ones up front in the user manual that go on and on and on about everything obvious (do not swing running power tool by its cord above your head, etc.) that you’re supposed to read thoroughly before taking the tool out of the box? They’re written by the underpaid employees of rich lawyers as part of a lucrative settlement when some poor person did swing the tool around and lost an ear thereby winning millions of dollars in court to be given to the lawyer.

Don’t be this person, which is to say that keeping your digits attached is much better than spending long hours without them in a courtroom. What’s my advice on how to keep all your digits? The lawyer will tell you it’s all those safety warnings. I’ll add that it’s important to listen to your intuition. This is that gut feeling that says this isn’t right or I’m not sure about this or I hope this works ok. If the tablesaw scares you, it’s for a very good reason. Leave it alone and use other tools. If the tool doesn’t act the way it should, there’s a reason. Stop and ask advice from someone who knows. Learn about the tool or technique and only use it on your own at the point that it no longer scares you.

Then and Now

I have a copy of Henley’s Twentieth Century Book of Recipes, Formulas and Processes: Containing Nearly Ten Thousand Selected Scientific, Chemical, Technical and Household Recipes, Formulas and Processes for Use in the Laboratory, the Office, the Workshop and in the Home, published in New York in 1907. Intended for the general public, Henley’s tells you how to make everything, from your own acid-proof wood finishes to food preservatives, foot powders, even zinc contact silver plating. But in close to eight hundred densely packed pages, there is not a single image or illustration, and there are few how-to instructions. To make the acid-proof wood finish, for example, the book simply tells you to boil copper sulfate and potassium chlorate salts until dissolved.

To many modern Americans, the directions in this book are dangerously incomplete, perhaps criminally. Will boiling these crystals give off noxious fumes? Do you add water? How much? Can they be boiled safely in a steel or aluminum pot? Where can you even buy these crystals? Henley’s is mute. While I’m sure many readers in 1907 did not know the answers to all these questions, many more did. Henley’s was a popular book.

In 2015, we no longer have the same foundation of practical knowledge or hand skills (or understanding of risk) that our ancestors did. The efficiencies of mass manufacturing has allowed each of us to focus on specialized professions—we simply don’t need to build or repair our own houses or furniture anymore; there’s someone else who specializes in that. Many of us lament this loss, looking back on earlier generations, amazed by their ability to do so much on their own.

But they did not have the internet, heated toilet seats or inexpensive Asian manufacturing integrated with global markets and high volume shipping capacities. With these things, we are far more productive, far less burdened by the work necessary to simply survive, and have far greater freedom to pursue other opportunities. We are now far less independent and far more interdependent. We are not worse off—we are just different.

Today, most people would think it slightly insane to make your own doors when you can buy a manufactured, pre-hung steel and plastic door at Lowe’s for $67. That’s not much less than three times the cost of this book.

Of course you won’t save any money making your own doors, or advance your career in selling widgets. You will, however, create beautiful, unique and useful objects—thereby acquiring the traditional skills of craftsmanship that have shaped our humanity: a main advantage, and consequence of the opposable thumb.

If we share anything with our handier ancestors from 1907, it’s the need for understanding and mastery of our daily environment. We may live in a world where merely opening the back of a phone voids the warranty, but we still can find deep satisfaction in creating some of the things we use.

Perhaps you have long experience working with your hands. Then enough said—this book will give you answers to your questions about making a door that won’t warp, crack or fail unexpectedly. But perhaps you’re new to the idea of making your own things, and a book seems like the right place to start. There are simple doors you can make and you’ll find them here, with how-to instructions shown step-by-step to help you make them right the first time.

And if you get a copy of Henley’s, you will know how to finish a door so it’s acid-proof—perfect for the Zombie Apocalypse, because, as we all know, by next year the TV zombies will know how to spit acid, if they don’t know already.

The Basic Challenges of Doormaking: the Origin of Traditions

In caveman times, men sat around playing with the fire while women did all the work. This was noticed, and so the first honey-do project was devised. Some might suggest that project was a table or a stool, or even a bowl. But I think the front door was man’s first honey-do project.

The cave is drafty, dear. And bears wander in too often. Why don’t you put down that flaming stick and make us a movable barrier that will serve to either open or close the way into our cave.

Durrrrrr, our common ancestor stalled for time to think his way out of this task.

Whatever you want to call it, dear. Just get busy.

Yes dear.

At this moment, the concept of the door was born—at one stroke solving the problems of keeping cold/animals/insects/nosy neighbors out of our homes, and heat/possessions/wandering toddlers/family secrets in our homes.

Now our common ancestor racked his brain to bring this great concept to life. What to use? Straw and animal skins might work, but were too flimsy—bears could easily paw or gnaw through them. Stone would stop a bear cold, but was too heavy and hard to work. That left wood: a durable material that wasn’t too heavy and was relatively easy to work, and yet would keep out the bears.

Carving a door out of a single slab of green wood to fit the cave entrance seemed like the easiest approach. And so our common ancestor tried it. But that door warped like a potato chip (though those hadn’t been invented yet—that would occur much later, in Greece), refusing to shut after the first week.

Nice property, but how to keep out the bears?

For his second door, he seasoned the plank beforehand, letting it dry for several years. It was more stable, but it still grew and shrunk depending on the season, tended to cup, stuck shut in the summer and left a gap in the winter. Then splits developed at the ends and it eventually broke itself apart.

For his third through 50th door, our common ancestor tried a variety of designs to solve an ever growing list of design challenges—and through this process understood the basics of making doors with wood. On the one hand, wood has a lot going for it:

Wood is relatively easy to shape (with tools)

Wood is relatively light compared to its strengths

Wood is a durable material

And it looks pretty good

And on the other, wood has a few core problems that have to be accommodated:

Wood is weak across the grain

Wood grows and shrinks according to the relative humidity

Certain woods get eaten by fungus and insects

Without a finish, wood silvers and degrades with UV light, oxygen and water

Discovering that wood is a reasonably complex material with a range of attributes that vary from species to species, tree to tree and even inch by inch kept our common ancestor pretty busy. Then consider that an exterior door will face winter on one side, and a warm interior on the other—huge temperature and humidity differences that stress the wood like nothing else. It quickly became evident that doors had a lot of difficult, even unique challenges. Hard-won solutions came with time and effort.

So before our first doormaking common ancestor died, he passed along a lot of valuable advice on making doors to his apprentice, who understood half of it because he was a teenager and not listening. But when that teenager grew up, he still made doors the same way because making them differently took more time and effort and they broke faster. This was the beginning of Tradition—the art of doing it the same way it has always been done because it works.

1 Practical Design Principles for Doors

While we can only imagine when and where the first solid wood doors were made, we certainly have been making them since long before the Egyptians walked around in profile. The amazing thing is just how similar wood doors are all over the world (including cabinet doors, gates and other variations): people everywhere largely reached the same engineering solutions and refined them on the anvil of everyday life to create traditions that have persisted, despite superficial stylistic differences. In short, there are good reasons why doors look like they do and have looked much the same for a long time.

Of course there’s a place for innovation and creativity—all doors do not look the same as tradition has width and depth. Within traditions are stylistic innovation and experimentation. However, we forget why we do things, so we make new mistakes to learn old lessons. The more you understand the reasons behind traditions, the more likely you’ll be successful when you make something new and unique.

If you’re just here to build one of the projects like a recipe, I’ll caution against it and recommend you read and absorb the whole book first. If you want to make doors on your own without following any of the projects, this chapter will help you understand the practical aspects of doormaking traditions, materials, hardware and building technique choices.

At the Fork in the Road, Go Both Ways—Answering the Age Old Question "What’s the Best Way to Do It?"

When I was young and starting out in the profession, everything was simple and easy. I knew of one good way to cut joinery, three good woods to use and one good finish. I had the answers.

Problems and failures, eventually taught me otherwise. Over time I learned more techniques, woods, finishes and other details that helped to get things right more often than before. Often I felt I found the best way after trying ten ways. But then the next problem argued against it, and I’d look for an eleventh.

Experience leads to a more refined decision making process: answers generally begin with a that depends and then a mulled solution that will probably work best. It doesn’t produce The Best Way. That doesn’t exist, and I don’t have it, no matter what I claim, as there is always tomorrow to prove the sum of history wrong.

For the beginner looking for a clear direction, projects with step-by-step instructions are just the ticket: they are a distillation of experience, choices made for you that should get you to a successful door if followed faithfully. Experience isn’t really transferable, but it can be created through doing. When you start making doors to your own design, without the help of step-by-step instructions, the basic principles in this section can serve as guides to minimize those pesky problems and failures.

DOOR PROPORTIONS

Standard door sizes range from 24 in. to 36 in. wide and 80 in. to 86 in. high.

Build doors to be rectangular, taller than they are wide, and relatively thin.

The tall rectangle is the basic shape of the human body and has been the basic shape of the door for ever (though with growing global obesity, we might be moving towards a square or circular door tradition).

Modern manufactured doors come in a few standard sizes—for example, 30 in. by 80 in. and 36 in. by 80 in. These are good proportions to stick with as they work, are within code, and look right. However, the beauty of a custom door is that you can make it however you like.

The maximum width I’d make a single door is a about 40 in., as adding width adds weight and stress on the higher hinges, causing them to bind and fail faster than they should. For doorways wider than that, I’d make a pair of doors that close in the middle.

Doors don’t need to be taller than 80 in. for any practical reason, unless you have a basketball player in the family or plan on building sailboats in your dining room that need a way out. That said, don’t think of 80 in. as a limit—wider doors tend to look better if they are proportionally taller. A grand double entry door I recently completed was 56 in. wide by 86 in. high. None of these good proportions are based on the golden rectangle. Sorry to disappoint the classicists.

Moving outside of the tall rectangle rule will add complication and impracticality, but perhaps add some interest. Curved top doors
