Napier’s Bones

. . .or Napier’s rods, but Napier’s Bones sounds so much more mysterious. I’ll explain what these are later (or you can read about it here), but in the meantime, here’s a couple of shots of the model and the actual cherry wood box for a set of Napier’s bones and a miniature copy of E. W. Hobson’s lecture about them and their history. I’m not sure this little project will fill a long-felt need in the miniature collecting world, but I couldn’t resist.

I’m back to working in wood! Nice little joinery there, huh?


  • Oh boy-does this bring back memories. My father made a set of these for me when I was about 7 yrs. old and taught me how to use them (I have since forgotten everything-no surprise there) and as I remember there was a board that went with them and was necessary for their use. Yes/No?

    Why in the world does this really appeal to me?

    I know what you mean – ah, the happy wasted hours my father spent trying to teach me to use a slide rule. I have a fascination with antique technology that I can’t comprehend. I just made a tray version last night – see post above. Unfortunately I haven’t manages to get them down to one-inch scale. The versions I’ve seen have bones about 5″ – 6″ long. But I persevere! The book is about 1 1/8″ x 3/4″, which will give you an idea of scale.
