Handy Chart for Determining the Length of Stock

100 years ago the Americans developed a chart for determining the length of stock. They used this chart when ordering stock or in checking up to see if enough material was on hand. This method of determining the length of stock can still be used today.

The inner circle of figures shown in the illustration represents the length in inches of the piece required, while the figures on the outside give the number of linear feet of stock necessary to make 100 pieces. For example, if the length of a piece as per order is 2 7/8 inches, and there is an allowance for cutting off of 1/8 inch, the total length of the piece would be 3 inches. Referring to the chart the figure 3 in the inner circle is opposite the figure 25 in the outer circle, which is the required number of feet for making 100 pieces; having this, the amount of stock for any number of pieces can easily be determined.

  1. Nice idea, but I’m confused. If I make a 1 ft long part – how can I get by with 96+ ft to make 100 pieces? And that’s without any kerf allowance that I see. Thought you’d like to know. Tom
