Author: Ezra DrissmanOne wonders if a green book store is one that sells only green related books. While the genre certainly has its strong showing, it is probably better to offer some variety in the books that are sold in the book store. It would be better to have the term "green book store" refer to the way that the business is run rather than the type of books that are sold there.

Band saw blades are one of the most commonly used tools when it comes to wood cutting. The band saw, like the scroll saw, is used primarily for cutting curved or shaping pieces of wood. Use of the miter gauge or tilting of the work table adds versatility and flexibility to this task of using a band saw. Another important function of a band saw is its ability to resaw or rip narrow pieces of wood. Using a band saw for this function is safer than with a table saw.The work table is slotted for use with a Miter Gauge that increases the accuracy of straight cuts. Because the table also tilts, the band saw will do ripping and crosscutting at angles of up to 45 degrees. A blade used for the band saw is a narrow metal strip, with sharp cutting teeth along one edge. The band saw runs around two large motorized pulleys or wheels that are mounted on a frame. Blades are available with various sizes of teeth. The number of teeth a blade should increase the harder the material you are working with is.Keep in mind that regardless of the manufacturer all saw blades need to be broken in. New blades are considered too sharp.If you cut with these sharp blades they can cause fracturing of the outer...more
