Threaded lid sphere box

Dick Coers

I'm doing a demo this Saturday for a turning gathering of 3 Illinois AAW clubs. The demo will be on spheres and I wanted to throw in something new. So this is proof of concept, will do a couple better ones before the event. Soft maple, 2 1/2" diameter, black pvc threads from plumbing fittings. Putting in the grooves was more difficult than I thought, and got a little tear out at the intersection point when I scrapped them in. More finish will be added, especially on the flange area. Something I didn't think about, the smaller diameter hollowed half of course sits on the table because of the weight. It would be nicer if the bigger area was on the bottom.

Very cool! If you're producing handouts for your demo, would you mind sharing them with us? I'd be there in person if I could!

Dick, you could undercut/hollow beneath the male portion of the threads to reduce the weight and perhaps the female section would be on the bottom.

Most of the threaded sphere boxes I have seen have had this problem if you consider it a problem. It doesn't bother me in the least.

Nice job.

I was thinking the same thing as Mike. I have have hollowed fairly extensively under the male thread portion on some of my gift ornaments to make them lighter.

I love the Sphere idea with the cuts on the outside. I've seen Mark StLeger do the threaded sphere several times but have never tried one myself. I remember one time Mark was chasing threads in a sphere and then had one heck of time getting it apart after turning the Sphere portion. There's nothing to hold onto to grip it. He said he wished he had waxed the threads and mating portion before turning the sphere.

Would love to see your demo. I always learn something especially from people like you who put the extra effort into preparing for a demo.
