I’ll admit it. I am not as fast as I’d like to be. I always think that I will get things done quicker than I do. And, I always say that things are done when I mean they are “basically done”, which means that I still have a few things left to do (therefore not done). I like to think of it as being optimistic. Well, while I am being “optimistic”, a lot of other things aren’t getting done (mostly because I am busy working on the thing that I thought was already done).
The one thing usually not getting done is sawing. After all, the logs aren’t going anywhere and a lot of them are just getting better with age. I’ll let them sit for a while, depending on the species, and try to play it just right for special things, like spalting, to happen. Sometimes I push it too far and the log rots and becomes unusable. Species like ash and maple, which have a lot of sapwood, need to be milled sooner than the rest. They (especially maple) will quickly stain, spalt and then rot, while others will be fine. I often use this rotting process as a gauge to decide which log to mill next. I like all of the logs I bring in, and I don’t want any of them to turn into dirt before they get turned into lumber.
Through the years, as I have kept tabs on the disintegrating logs, I have learned what it means to be “durable”. In the books about different species of wood, they always list their durability, which I thought meant how they handle wear and tear, like from a hammer, but they mean from the weather. Turns out some woods last longer outside than others. I knew this, of course, but only from reading it. Now, after all of my “wood collecting”, I know it from watching it happen. Some woods go fast, but some never seem to go. And, they are not necessarily the first ones to come to mind.
I was inspired to write this because of the two that are extremely durable, but no one ever thinks to use outside – two of my best friends – walnut and cherry. These two just don’t rot. I should say the heartwood doesn’t rot. The sapwood on both of them rots as fast as any other sapwood, but the heartwood doesn’t rot. I commonly find old logs with no bark and sapwood that just flakes off in my hand, but the heartwood is fine. It might have cracks in it from the log drying out or bug holes from sitting too long, but the heartwood will be just as solid as the day it was cut down.
Of the species I mill, these are not the only ones that perform great outside, but they are the surprises. I bet almost no one would think of using walnut or cherry outside. They always end up inside because they are so nice, maybe too nice to put outside. I will tell you that this one has me baffled, and as of yet, I have no idea why this is. However, my main interest is to spread the word that walnut and cherry are great outdoor choices. Walnut may not be the best because the price is going up, but cherry is becoming an even better choice as its price is on the decline. If you don’t mind a few knots in your outdoor work, common-grade cherry is very affordable. And, if you are doing a high-end outdoor piece clear walnut may make sense. It is more expensive than Ipe (an imported wood great for outdoor work), but it is easier to work with and it just feels right to use an American wood.
Again, the sole reason I know that these woods are durable is from my own experience. If I have a walnut or cherry log and it doesn’t get cut right away, I don’t sweat it. I know that years down the road that logs from these two species will still have solid wood in them, while others have rotted away. The best example I have is from a recent post about a walnut that I found on the Missouri River. It was the driftiest piece of driftwood you will ever find and the inside still looked like new (click here to check out the post and video from the picture above and to see the inside of the log).
