Gary, I'm going to have to give flip-flop a try next time I do sun lines.
Paul's suggestion also looks like a good one to me.
Because I often had to plot in minuscule spaces - the lid of an ice box or kneeling by a settee berth - I soon gave up my 4-inch parallel rules (too much slip). First I used a circular protractor for Zn and a ruler for the LOP. Finally I settled on the Douglas 5-inch square protractor for both.

OR, don't draw the ZN line in the first place. Use the "flip-flop" method, see:Download the entire celestial navigation section from the current Air Force navigation manual, AFPAM 11-216 (2001), here:gl

Sam, thanks for posting the Buckley PDF. His last instruction - "Erase the Zn line" made me grin. It's not something I ever did, but it would sure reduce (pun intended) the clutter of the plot, especially with multi-star shots.HewittCopyright? Why have a time limit on it? How about forever?Give you an example- Buckleys video about Simplified Celestial navigation used to be on Youtube in its entirety. Bennett Marine (or whoever they are) sells the video and I assume had the complete video removed from Youtube as I suspect they think, or claim, they hold the copyright to it. Also, Youtube claims ownership of all videos put up on it's site as Amazon claims the right to copy and manufacture items you put up to sell on it regardless of Patent or Copyright. That sounds like theft to me.Yet, you can get Buckley's entire worksheet, NA and HO 249 sheets off of Yahoo https://lib.store.yahoo.net/lib/landfallnav/CELESTIALNAVIGATIONSTUDYGUIDE.pdfOnly because of the PDF above was I able to understand sextant Sun sight reductions as it was explained in simple to understand terms and not by some math "teacher" who typically can only explain their art to the initiated. I have to reflect that while I'm not good at math my guess is most navigators of old had little or no education.Copyright is only to keep us "little people" from copying something. The machine, the corporations just take it.
