    INTRODUCTION

    As we enjoy an evening in the workshop, it is easy to forget that the craft of woodworking encompasses a surprisingly large body of information. Much of that information is learned only through considerable practice and experience. And, once learned, it is usually applied to the task at hand with little thought or effort. An experienced woodworker knows, almost intuitively, what to do and how to do it.

    But even veteran woodworkers understand that practice, experience and intuition are not always enough. Despite what seems to be second nature, it’s often necessary to find an important bit of information in order to move a project forward. Usually, however, that bit of information is found only after a lengthy search through a pile of woodworking books, magazines, owner’s manuals and shop-worn notes. And, of course, the search too often comes up empty.

    This book is an effort to make that search considerably easier. Here, in a single volume, is an easy-to-understand compilation of the many facts, figures and formulas that are important to every woodworker. From shop geometry to lumber grades to drill press speeds, The Handy Shop Reference provides an extensive storehouse of valuable woodworking data.

    This is a book to be used, not admired. Keep it near your workbench. My sincere hope is that you often find yourself reaching for it, and that it quickly provides you with all the information you need.

    Have fun and work safely.

    Chapter One

    WOODWORKING MATH

    BASIC GEOMETRY FOR WOODWORKERS

    An understanding of basic geometry is useful to woodworkers. Indeed, when you consider that every woodworking project is made from parts that form straight lines, curved lines or a combination of the two, it is clear that geometry is very much a part of the workshop.

    Angles

    The space between two lines that meet is called an angle. An angle is usually measured in degrees.

    Right Angle

    The angle formed by a line perpendicular to another line. A right angle measures 90°.

    Acute Angle

    An angle measuring less than a right angle.

    Obtuse Angle

    An angle larger than a right angle, but less than 180°.

    Polygons

    A polygon is a closed plane figure that has three or more sides and angles. A polygon with all angles equal and all equal-length sides is called a regular polygon. Some of the common polygons are:

    Triangles

    A triangle is a polygon with three sides and three angles. The sum of the three angles is always 180°.

    Right Triangle

    A triangle with one angle at 90°

    Scalene Triangle

    A triangle with all sides unequal

    Equilateral Triangle

    A triangle with all sides of equal length.

    Obtuse Triangle

    A triangle with one angle obtuse (greater than 90°)

    Isosceles Triangle

    A triangle with two sides of equal length

    Quadrilaterals

    A quadrilateral is a polygon that has four sides and four angles. The sum of the four angles is always 360°.

    Rectangle

    A four-sided plane figure with four right angles

    Square

    A four-sided plane figure with four right angles and four equal-length sides

    Rhomboid

    A four-sided plane figure with all sides parallel, adjacent sides unequal, and usually having two acute angles and two obtuse angles

    Rhombus

    A four-sided plane figure with all sides equal-length and parallel, usually having two acute angles and two obtuse angles

    Trapezoid

    A four-sided plane figure with two sides parallel and two sides not parallel

    Trapezium

    A four-sided plane figure having no sides parallel

    Other Polygons

    Regular Pentagon

    A plane figure having five equal-length sides and five equal angles

    Regular Hexagon

    A plane figure having six equal-length sides and six equal angles

    Regular Octagon

    A plane figure having eight equal-length sides and eight equal angles

    Regular Decagon

    A plane figure having 10 equal-length sides and 10 equal angles

    Regular Dodecagon

    A plane figure having 12 equal-length sides and 12 equal angles

    Circles

    A circle is a closed curve, with all points on the curve equally distant from the center.

    Radius

    A straight line extending from the center of the circle to any point on the circle

    Diameter

    A straight line that passes through the center of a circle and extends from one side of the circle to the other

    Chord

    A straight line connecting two points on a circle

    Tangent

    A straight line that touches a circle at only one point

    Segment

    That part of a circle cut off by a straight line

    Area Formulas

    Area is a measure of the amount of surface of an object. Square units of measurement (square inches, square feet, square millimeters, square meters, etc.) are used to describe area.

    Triangle

    Area = ½B × H

    where: B = length of the triangle base; H = height of the triangle

    Example

    B = 12"

    H = 8"

    Area = ½(12) × 8

    = 6 × 8

    = 48 square inches

    Square

    Area = S × S

    where: S = length of the sides

    Example

    S = 6"

    Area = 6 × 6

    = 36 square inches
