174 - Accoya

Halloween is upon us and let's look at the ancient art of vampire hunting. We all know you drive a wooden stake through the heart of a vampire but which wood is best? In this episode I give you a top 10 list of the ultimate vampire hunting specification.

The Sassafras was the first North American export. Or rather its roots and bark were as the miracle cure that Europe clamored for. The lumber excitement came much later and was the default for fence posts for farmers until the pressure treated stuff put it out of business. Today Sassafras is making a comeback for exterior uses like decking and siding. It's oakey texture makes it familar buts its color variety and easy workability make it a nice change from difficult to work oaks.

Sticker stain is more about the drying technique than the material used for the stickers themselves. Certainly the stickers play a role but the key is getting the lumber below the saturation point quickly to stop oxidization and enzymatic reactions. The stain can ruin beautiful lumber and go so deep it can't be planed away. Additionally I dive into the Red Oak and White Oak market trends.

Limba is sold both as Black Limba and White Limba. It is the same species. Limba is actually more like White Limba and the Black streaks that make Black Limba are more of a form of spalting and staining. Its a species that you have probably seen already but didn't know it. From famous guitars by Gibson to modern interiors and furniture and now thermally modified siding in the form of Frake. The species is widely used and largely unknown.

So you want to use reclaimed wood. But where did it actually come from and what kind of nasty might it have been exposed to along the way? In this episode I talk about where reclaimed wood comes from and what potential hazards might show up and how to test for them. Basically a green light, yellow light, and red light ranking system to think about when considering reclaimed woods.

Accoya is a chemically modified wood to make it water and rot resistant and extremely stable. Not to be confused with chemical treatment like pressure treated pine, the chemical modification or acetylation process is non toxic and permanent. Accoya warrantees their products for above and in ground contact and has transformed the humble, planatation grown Radiata Pine into a wonder material.

The White Pine was the prominent tree across colonial America and it was thought to be an endless supply. Over 600 billion board feet of White Pine was logged after the Revolutionary War until the mid 1800s. When New England went dry, we turned west to the great lakes states and removed hundreds of billions more board feet. This removal of the "limitless" resource sparked the modern conservation movment and created the science that today we call silviculture. This is the story of the White Pine and why it should have a place on your workbench.

The 2x4. Its the basic piece of modern stick frame construction. But it is not actually 2" by 4". Many of us know this, but do we know why the size has changed but the name stayed the same. Moreover how did anyone even start with those dimensions. This single piece of lumber is a representation of all the changes that have occured in the building trades and the optimization of forestry, economics, and manufacturiung. Its not a measure but a convergence of optimization.

Its not actually a Cedar but who cares. Western Redcedar is an amazing exterior wood used in everything form boats to guitars, decks, shingles, siding and pergolas. Its known as the tree of life among the native peoples of the PNW. This tree produces some amazingly clear vertical grain boards and as you might expect, has gotten pretty darn expensive these days.

Spalting is essential fungal rot in wood. But it is pretty and therefore people seek it out and even go so far as to "grow" their own. In this episode I discuss the 3 types of spalting found in wood and even discuss the fungi responsible for it.
