I have tried to make the circular slide rule template precise and accurate, but do not promise that it is error free. Other factors which influence the accuracy of the circular slide rule are: (a) the quality of your PostScript printer, (b) careful assembly, and (c) your skill as a user. If you use your circular slide rule for important calculations, please check the result by an independent method.
