155 Composite Lumber

Today I fight my strong wood bias and take time to talk about composite lumber. All the various plastic boards you will find on the market from wood flour and plastic slurry to polyethylene capped boards and fully plastic HDPE or PVC. What you should know about the differences and how you can actually work with this stuff.

My featured species this episode is Buckeye. Its a non commercial species but not terribly hard to find and has some unique color and high propensity to form burls. But the real meat of this show is a look at how a forest regenerates after a disturbance like a fire or logging. The successional forest model helps us understand how forestry managers can foster a healthy forest through logging. But then we look at how bugs and blights can disrupt the succession model even further.

How do you find unusual and typically non commercial wood species? In this episode I give some tips to help the listener build a network of wood sources.

Monkeypod is a great timber coming out of Costa Rica that is almost entirely FSC. It is often sold as wider slabs due to the lighter weight and the way it is sawn in the jungle. A great alternative to many of the tropical species out there like Koa and Blackwood or even some of the fancy Rosewoods.

Let's define plantations and natural forests and talk about what we can expects from the lumber coming from plantations. Also how plantations can evolve into natural forests. Ultimately why do we need plantations and why do we need natural forests. Also answer some questions about air drying and dealing with bugs as well as drying large timbers.

It could be said that Hickory built America. Hickory's properties made the American felling axe possible with its extremely high MOR and MOE values. Today we discuss this great American wood and why you need to add it to your repertoire of woods.

Douglas Fir is a species we find everywhere. So much so that we may not even know we are looking at it. It has two distinctly different markets: construction lumber and fine (very fine) lumber for cladding, decking, soffits, and even furniture. The species has had a rebirth of late and is outcompeting Western Red Cedar in the forests.

What are the markets for the common species of lumber you find at your hardwood lumber dealer. I delve into who is buying what and for what. Plus further discussion about logging in national forest land, wood movement and heat, buying veneer, and harvesting Boxwood.

This time I featured Parota or Guanacaste. The Costa Rican national tree and known for being avialable in wide slabs of red, ribbony goodness. I also discuss how to know if the wood you are buying will be good for the project you intend to build, and fungus..mmmm fungus.

Time to revisit the old stud torn from a building that is compared to the new stud fresh from the big box store. But more to the point, let's take a look at how wood is sawn from a log to meet market demands. Not that trees don't grow like they use to but do we actually need them that way too.
