Automatic TRANSCRIPT

Steep breath in let it out slowly and off. We go tonight. Were returning to a practical handbook woodworking for beginners manual for amateurs by charles g wheeler b s with over seven hundred illustrations published in eighteen. Ninety nine by charles g wheeler and the knickerbocker press of new york. Let's pick up where we left off chapter three would before you could make anything successfully. You must have not merely would but the right kind of would for the purpose. There are also choice cuts in lumber s the butcher says of meat and judicious selection of the stock often makes all the difference between a good job and a poor one so let us examine a log and follow it through the saw mill. You have of course seen the rings or circular lines on the ends of pieces of wood. These are called the annual rings and each ring marks. A new layer of wood added to the tree. For as perhaps you have learned the trees we use for woodworking grow by adding new layers of wood on the outside. Examine the ends of pieces of wood of various kinds in some pieces. These rings will be very plain in others. they will be quite indistinct. Notice that the would nearest the bark known as the sap would usually looks different from the inner would is called the heart in some trees. You will see raise or lines radiating from the center and known as the mention larry raise because they spring from the piff called in latin. Mcadoo la you'll see from figure ten. That layers of wood are also shown in the lines of what we call the grain on the surface of a piece of wood. Cut lengthways and that the lines of the grain are continuations of the annual rings. You will also notice at the ends of timber after the seasoning has begun cracks radiating from the centre her showing the natural lines of cleavage or separation. The way the log is sawed is important though you might naturally think that the only thing is to saad any way that will give pieces of the required size and shape why is greenwood heavier and softer than dry wood. And the sap would of green timber softer than the heart. Because of the sap or water contained the amount of water is sometimes even as much as fifty percent of the weight of the wood but the quantity depends upon the kind of tree the season et cetera. Now the more water.
