Looking for old article

[Michael Brolly]

I am looking for an article from about 8 years ago. It was about turning geometricly odd forms. It involved doing two turnings and cutting them in half and gluing them back in a different orientation. The shapes have a specific name that I cannot remember. I have a gifted student that I believe could run with that type of stuff.
Thank You,
Michael

Do you maybe mean inside-out turning? If you mean off-center or multi-axis turning, there's tons of articles in the Woodturner and Fundamentals archives.. there's an article on inside-out candleholder in June 2013 issue of Woodturner (member archives on the aaw site)

You might be thinking of ribbons as well. If you visit Malcolm Tibbett’s website, you will find endless inspiration for geometric, deconstruction/ reconstruction of forms! Have fun!!

 

[Michael Brolly]

No, there is a word for it in Geometry. They have weird shapes but can still roll like a sphere. I can't remeber that name. I am pretty sure the guy who wrote it was a math professor.

One of my favorite classes was with Hans Weissflog, we made these forms with the added challenge of making them into boxes.
I've seen them made with paper joints, split and re-glued, I think I remember someone used magnets. Lots of fun...

Thanks but not Hans, I know him. I think if I could get the names of some of those forms I could find the article. Anyone know that name?

Initially I would say you are interested in the split-turnings of Stephen Hogbin.
But, maybe you are referring to "femispheres". David Springett? Below website of Peter Rand

Femispheres 

 

[Michael Brolly]

Yes, thank you. It was Femisphes.

Best,

This thread has been moved from the Introductions Forum to the Woodturning Discussion forum.

"Femisphere" is one type of the more general term "Streptohedron" See American Woodturner August 2013. Also, even better, the book Woodturning Full Circle by David Springett. At first, even after reading the book, they seem impossibly complex. But after a couple hours, you can be an expert of the simpler forms.
I demonstrated these for my club in Cleveland. you can see the video at

Very good video.

This is not turning, it's 3 d printing,which I know nothing about. It will give you more ideas. Google, make anything, sphericon. He has a lot of different videos. Hope you can find it.
