As you did, I had to figure out a way to make the thing. Some of my ideas worked well, others not so. At the time, I couldn't find a thread on the subject. There is one now!

A long time ago, I would periodically have to realign my slide rule. (Yeah, that's how old I am!) Amazing how little misalignment it takes to make 5x5 equal 24.8!
