For anyone who may be interested in making a cel nav slide rule with trig scales on both slide and body (aka stator) a correction to my earlier post: The slide is from a Keuffel & Esser 4070-3 Duplex Trig rule. The body is a K&E 4090-3 Log Log Duplex Trig rule. The 3 scales on the stator are T, S2, S1. Many thanks to Alan for asking about this. It made me go and get the rule out and look at it, which is always pleasant. Hewitt Sent from my iPad
