>>I think the problem with the pictured degrees-minutes scale is that it has 4 different heights of lines<<
I agree with you, Bill. I have been cooking up various line heights...and I think it is possible to do a good job on this, one that will make the rule legible. I am a little surprised that some of the regular manufactuers in the golden age of slide rules didn't work a bit harder on that very issue (particularly for those rules that WERE set up in degrees and minutes).
