For those who prefer pencil and paper or scale models for design work, a scale rule is invaluable. This one departs from the conventional three-lobed format, which not only eliminates the need to rotate and flip the rule to obtain the desired scale, but also avoids the risk of error inherent in that process.
Instead, a rotating indicator bar can be turned to display any of six common scales, all of which read left to right and remain fixed until reset to a different scale. The opposite edge is marked as a standard 12" rule graduated in 32nds.
Made of aluminum with an easy-to-read matte finish that you can mark with a pencil, the rule includes 1/16, 1/8, 3/16, 1/4, 3/8 and 1/2 scale ratios, suitable for common woodworking applications.
