nautical slide rule

Joe S · 04-13-08, 04:46 AM

I just found (Saturday) a US Navy nautical slide rule, marked "U.S. Navy bureau of Ships, Mark 1, Mod.O" dated 1959. Its a very neat device for time -distance speed calculations. It has two scales, one for nautical miles travelled and one for yards traavelled. I did a quick search online and found that new ones are available , as stated in other posts, for about $20. I got mine for $5 but thats the luck of the draw. At any rate, I havent used it in a mission yet but it will definately be useful. Joe S

Can you post a pic? I might be able to replicate it for printing, laminating and building one at home

This ties in with what we're doing on the Real Navigation thread.

Here's a simplified model I made for use navigating. I you post a pic i might be able to make it look more authentic to the period.

Better yet (for me), can you post a link? I'd be glad to just buy one.

Here is a link to a 'nautical slide rule 105', not sure if this is the same or similar device that Joe mentioned.

The navy rule was adapted for aircraft, and is known as an e6b. Its a radial slide rule, with C and D scales, with conversion factors for all kinds of units. Plus the board let you compute wind corrections.
