All articles in seventh grade will be made of White Pine or Yellow Poplar; those in eighth grade of Chestnut.

Stock bills are not needed for articles composed of one piece of material only.

Finished sizes are the sizes to which the pieces are to be planed. Your drawing will tell you these sizes.

Pieces of irregular shape are to be figured at their widest and longest dimensions.

Cutting sizes are obtained from the finished sizes by adding 14″ to the width and 12″ to the length. Cutting sizes are the sizes to which you work in sawing out the stock preparatory to planing it.

All stock will be mill-planed on two surfaces to the correct thickness except that for the ring toss, spool holder, game-board, and laundry register. Thickness of mill-planed stock will be the same whether for finished sizes or cutting sizes. On rough stock, or stock that has not been mill-planed, if the finished size is 34″ thick the cutting size will be 1″ thick.

Sometimes it is possible to save material by combining two irregular pieces. The finished stock sizes will indicate the number of pieces while the cutting size will indicate the size of the single piece from which they are to be cut.

Remember that length always means “along the grain of the wood,” and that a piece may be wider than long. Under the word “Pieces” put the number of pieces that are of the same size.

In the elementary schools the form of stock bill used should be as simple and explicit as is possible. The appended form is one that has proven satisfactory. That it may be in convenient form for student use, it has been included with “Projects in Beginning Woodwork and Mechanical Drawing,” as also is the Form for Price List and Estimate of Cost.
