Pattern-Making by G. H. Willard explains a specialized branch of woodworking in which the finished wooden object becomes a tool for producing a metal casting. Published by the Popular Mechanics Company in 1910, the book adds chapters on core-making and molding and advertises 312 illustrations on its title page.
Learning the pattern maker’s trade
The opening chapter considers the education and experience of a pattern maker. Drawing, practical work and familiarity with the foundry appear together because the wooden pattern must serve a process beyond the bench where it is made.
Willard introduces shrinkage and the finishing of patterns early in the discussion. These subjects establish that a pattern is not simply a wooden copy of a finished casting: its dimensions and treatment must account for what happens during molding and metalworking.
This makes the book useful for readers who already understand some ordinary woodwork but want to see how its methods change when precision, repeatability and foundry requirements become the governing concerns.
Tools, timber and joints
The tool chapter includes chisels, gouges, planes, braces, bits, gauges, saws and other equipment. Selecting a kit and making a toolbox are treated as part of preparing for practical work.
The discussion of wood covers selection, quarter-sawing and flat-sawing, judging lumber, gluing and avoiding warping. Willard connects the behavior of the material with the reliability of the pattern made from it.
Several forms of joint follow, including lap joints, tongue-and-groove work, miters and dovetails. The reader can see how familiar woodworking connections contribute to the construction of shapes that may be too large or complicated to cut from a single piece.
Turning and machine work
The book proceeds through turning and the use of machine tools. Lathes and their accessories appear alongside the methods used to shape round components and prepare the work they require.
Later chapters discuss scroll or jig saws, band saws, jointers, planers, boring machines, routing and trimming equipment. Drawings relate the machine or tool arrangement to the operation under discussion.
These chapters preserve the equipment and working methods of the period. They are useful for understanding historical shop practice, while actual machine operation requires current training and guidance for the equipment being used.
Building practical patterns
The chapters on simple patterns connect drawings and sketches with construction. Willard considers working from a broken casting, calculating the finish, making split patterns and following a pattern through to its casting.
Successive examples include cores, core bars, corner cutting and fillets. The examples show why apparently small details can matter: a shape that is easy to make in wood may need alteration before it works conveniently in a mold.
The illustrations support this progression by showing the relationships among components. Readers studying traditional pattern work can compare an assembled form with the separate pieces and allowances needed to produce it.
Special patterns and molding
Later material extends into more specialized pattern work, including stove patterns, metal patterns and molding-machine work. Willard discusses the need for close measurement and uniformity when a pattern must serve repeated production.
The added core-making and molding material broadens the view beyond the wooden model. It helps explain what the pattern maker’s choices mean to the people preparing the mold and the core.
For workshop historians, this connection is one of the book’s strengths. It follows a craft through its relationships with adjacent trades rather than presenting its techniques as isolated exercises.
Who will find it useful
This free ebook suits woodworkers exploring foundry patterns, readers studying mechanical trades and researchers interpreting older shop drawings. It offers a practical sequence from tools and stock preparation to examples and specialized production methods.
The numerous drawings reward comparison with the accompanying text. A figure often illustrates one stage of construction or one feature of a larger arrangement, so the explanation around it supplies the purpose and assumptions behind the shape.
