I'm not sure this is the best place to ask, but it is math related. Where can I purchase Napier's Bones (rods)? I've been searching around the web and I haven't really been able to find anywhere that sells them.

Avoid the website mentioned in answer number 2 above. I make presentations at rendezvous all over the Midwest and at my seminar I demonstrates Napier's Bones. I, unfortunately, bought a set from an eBay dealer who sells the very same set, http://www.uniquecanes.com. The construction was terrible. The rods were not even square. The tabulat's index rod was not square to the tabulat, and the silk-screen printing did not align correctly, especially for the square root and cube root rods. The box the set came in, however, was well constructed. I had a great deal of difficulty trying to convince "ajsfixit" to make amends. He never did. the price of the set was approx $80,but I think it is now available for around $45. Finally, the set is not a replication of Napier's Rods, if you're interested in historical accuracy. My recommendation: depending on how authentic you desire, study up on the rods via Google and then have a local craftsman make a set for you. |

If you need something to use like Napier's bones, I think the simplest solution is to build them yourself with large popsicle sticks that you can find in most craft shops. Glue an appropriate printout. A student of mine did that, and it worked fine. |

On Amazon.com by doing a seach, e.g. this one Also, I'm not sure this question belongs to Math Overflow (and an answer was obtained by a simple Google search) so I downvoted it. |
