I think David Springett's article about cutting, rotating and gluing together solid geometric forms is fascinating, and I look forward to the next article in his series. "Woodturning" Spring 2004 No.135 pg. 7-11. A nice extra issue. Thanks, Mark.
I haven't attempted the cylinder or the regular polygons yet, but the cones result in quite distinctive forms, easily made. As with bias turning or cutting cylindrical segments to twist and glue into serpentine shapes or multicenter work, these forms although rounded aren't 'bowl' round. They don't require the specialized equipment and expert craftsmanship needed to make Chinese balls, lattice rings, true ellipses or ornamental work. Most of us cannot begin to come close to a Crabbe, Holder, Hosaluk, Darlow, Volmer or Weissflog. We don't have rose engines, pumping lathes, elliptical chucks, multi-layer chisels and wouldn't know how to use them, if we did. Speak for yourself, Arch!
I believe that these sphericons and streptohedrons will be an addition to the 'do-able and not quite round' projects that we average turners make as a respite from yet another round bowl or vase. I'm not all that sure about staphlohedrons or the feared hedron virus. ;) I hope that some of you, after studying Springett's article, will share your opinions here .
Regards to all, Arch
