It is 2" in size. https://picasaweb.google.com/lh/phot...eat=directlink Are there "official" dimensions for the sizes of the inner cubes, or would some kind of scaling algorithm count? (you know, like each inner cube 0.8x or 0.9x the size of its "parent?") I kind of have nothing but spare time these days, and I'd _love_ to at least draw one up on my borrowed AutoCad, and might even get permission from Joe the Machinist (Yes, I actually have a coworker named Joe, who is a real live machinist) to use the lathe and mill in the shop to try to make one on my own. It'd also be really interesting to just draw one up in my spare time and ask him if he'd like to estimate it. ;-) Is the defining attribute to qualify as a "Turner's cube" simply the fact that it's cubes within cubes with thru-holes? Google is my friend, but won't tell me what dimensions qualify it as "Turner's" - my first thought would be to use some kind of geometric ratio from cube to cube, rather than fixed intervals, but how do I find that out? Or is it primarily an exercise in CNC programming, as opposed to doing it "by hand," as it were? Thanks, Rich |

But if you need to get deep milling marks out, you can count on angle sharpness suffering in the indiscriminacy of the process. I looked for Turner's cubes on eBay once and only saw some cheesy plastics. You might try a metal with an apparent color turn away from aluminum, say bronze/brass, to gauge differential customer interest. A nice historical blurb on the history of the cubes and their significance in evaluating a machinists skills would be good alongside some nice poetic quote about "world's within worlds", "atoms within mass", "geometric projection", etcetera. Punchy lines are great but the copywriter's guide is that interested clients will read all they find interesting. Your descriptive powers will not have insignificant result. If you ever read the blurbs accompanying the "pet rock" phenomenon, there's proof. Regards, Edward Hennessey |
