How To Turn Perfect Hollow Sphere - No Jig

I've turned many spheres and have combined two techniques to make them perfect without a jig. But at a club demo, I was challenged to turn a hollow sphere. My response - sure. But, here's the proof.
Using the process, I've described in previous videos, the only difference is to stretch out the center of the sphere while still an octagon. In this case, I hollowed the sphere, then glued it back together again. Similarly, I could create friction slip joint or thread the joint. After gluing or joining the halves back together, continue the process from where it was interrupted.
My hollow cherry sphere is 3" diameter. It weights 75 grams = about 63 grams less than a similar solid cherry sphere. The finish is beeswax and mineral oil.
For basic sphere turning, please see my video - Woodturning Essentials - Octagon Method For Perfect Spheres at • Woodturning Essentials...
Enjoy!

The "stretch" in the middle was the key to what I have been missing in hollowing. Brilliant! Thanks.
Somewhat of an intermission.

Alan The way you set up the spigots on each end, then turned the inside was brilliant. Great technique I will certainly try. Sam
It is a great technique that avoids me having to buy a jig.

Not for a beginner. 8-| Nice
I agree for the hollow sphere.
However, smaller solid spheres should be on every beginners list. A sphere is a basic skill to be mastered.
