The Bygrave is set up to solve equations involving the division or multiplication of Cosines and Cotangents, and so I am not sure that the Bygrave slide rule can be used to solve the equations given in Frank's "Easy Lunars".

Ha! I did once derive the equations used for the Bygrave slide rule and a tortuous journey it was too! If anybody is interested, I will dig it out.
I don't have much interest in slide rules personally so I wouldn't know how to set it up. But it should be straight-forward, right?
