Woods the Difference?

As a woodworker we spend our time working with wood. But how well do we know this material? Do you know how a piece of wood is going to plane? Do you know how it will react to changes in humidity? Did you pick the right piece for the job? Is it the right species? Before I got into traditional woodworking I thought the old-timers spent an incredible amount of energy to do the most basic of operations and I was thankful for all the power tools at my disposal. I couldn’t have been more wrong. Many of our traditional woodworking forefathers had what seemed to be a much better connection to the wood and how it could be used and worked.

“They were friends, as only a craftsman can be, with timber and iron. The grain of the wood told secrets to them.” – George Sturt, 1923

The old timers used this knowledge to work the wood more efficiently with the tools they had on hand. They took advantage of wood’s strength in joinery, took advantage of planes of weakness in splitting wood, worked green wood when it was advantageous and dried wood as needed. They selected species suited to the task at hand and availability, they used parts of the tree like crotches, taproots and burls for purposes they were supremely suited for. They read the grain of the wood as they sized it up and felt how it handled when planed by hand.

This information is not dead to us in the modern world, but it takes some digging to find good sources and there is no substitute for getting out in the shop, experimenting with as many species as you can get your hands on and developing that close relationship to the wood. The woods are still out there waiting for you to make that connection.

The first step your journey to understanding wood is to learn the basics — what are the most prevalent wood species in your area and what are they most often used for? The info-graphic below is a great first step on this quest:

The next step is to understand and identify the woods you have to work with. The seminal modern references on both of these topics were written by R. Bruce Hoadley in his books “Identifying Wood: Accurate Results with Simple Tools” and “Understanding Wood: A Craftsman’s Guide to Wood Technology”. Both are excellent additions to your woodworking library and wonderful reference books, but if you plan to read them cover to cover be prepared for some sometimes dry reading material. I love that I can look up the coefficient of expansion of a given species but that is not an everyday need. If you want a more craftsman to craftsman introduction to wood as a material you might want to check out With the Grain: A Craftsman’s Guide to Understanding Wood’ by Christian Becksvoort. This book gives a nice crash course in how wood grows and works, how to identify common species and even a bit on how to grow and harvest your own wood.

What if I don’t want to share in all your fancy book learning?

While I am a bookworm I know that is not for everyone and that’s fine too. The board itself will tell you many of its secrets if you know how to listen. Grab a board you have on hand and go through the basic exercise of flattening it with a plane. The board will tell you its grain orientation — it will tear out if you are going against the grain. Spend some time with the board. Let it sit overnight in your shop and see if that flattened board moves at all. It will tell you when it reaches equilibrium with your current shop conditions. Experiment with your favorite finishes — the wood will tell you how it likes to react to that finish. Each minute you spend working with this material it will reveal more information that helps you improve your relationship with the material. If you are patient, spend some quality time with your hand tools and your wood, your skills and relationship will improve. In time you’ll be able to size up a board at the lumber yard and visualize how you are going to use it. You’ll break out your planes and get a feel for a given piece of wood — is it planing nicely or does it need to be coerced? Have you finished the board in such a way that your finish will turn out the way you want?  Does the species have the characteristics you need for this application? The investment in this relationship will pay dividends throughout your woodworking career. Your ability to listen to the secrets the wood has to share with you will make all the difference in the speed, results and enjoyment you get from your woodworking.

It’s time to get out into the workshop and and start that relationship….

Take care,

P.S. A big thank you to Peter JS for sharing the above info-graphic with me. His company made the above graphic for their client furnitureuk.co.uk and said that we could share it here on the blog.

    1. You’re correct, those are both good catches. I suspect the graphic was put together by folks that are not necessarily woodworkers.

      If I had to guess I would bet the author likely did a quick google and saw Eucalyptus obliqua, commonly known as Australian Oak and figured that was an oak. And similarly I’ve seen some mention of a few American redwoods being planted in Germany as ornamental experiments etc.

      There’s no such thing as a free lunch, and was surprised when I was contacted about this content. In the weeks since then I’ve seen several other folks post this same graphic as the creator is apparently using it as a guerrilla marketing tactic — if I would have known that ahead of time I may not have used it. On the whole its still more positive than not and hope for some folks who are really new to woodworking that it will be useful.

      Have a nice weekend.

      Take care,
      -Bill
