Never having turned a sphere previously but when asked if I could I said sure no problem. I got an initial order for 4×4” diam and 2 half 4” spheres, pic 3 they were not perfect but were good enough as these would be covered in leather. Pic 4 shows a sphere held in rubber chucky (see rubber chucky web site) and it became easier to get them spot on. Pic 1 are segmented spheres pic 2 piece of Oregon was turned using the above chucks.
The shells were addictive but I these have me by the balls (turning of course) and have a few ideas rolling around in the head.

Good result for for first attempt. Never heard about rubber chuck. I made my own wooden chuck. But it did not work properly. now I depend on my hand and eye.

No “balls up” with these ones Mate, look nice & even to my old eyes.
You know, there is probably more ideas on turning methods for spheres than spheres actually turned, looks like you sorted one that works real fine, nice job Bob
cheers
pete

Hope your Mates up in Syd’ are doing OK with that horrendous storm, looks real bad mate

I got it, Pet. I’m fine. Only I lost one day in the main’s shed. The floor of the shed was in 10 cm flood.
Thank you for your concern.

Bob those are cool. Look really well rounded. Did you use a jig to turn or by hand. I have used the rubber chuck and not happy with them.

Thanks Ron, I turned by hand, used calipers, sight and feel turning the ones in pic 1. Tried the rubber chuck with the others and have a 50/50 opinion of their use. Thanks Sam and Pete, this project has got me back on the lathe but had to clear the cobwebs off.

They turned out real good, Bob. Glad to see you had a project that got you back on the lathe. On that rubber chucky, is that sphere held in there just by pressure and can you turn the piece held like that or just sand it?

Cheers, Jim

Thanks Jim, the sphere can be turned while held in the chucks using a live center which the chucks screw onto.
I first turned the sphere leaving the spigots either end and putting a pencil mark down the center of the sphere before transferring to the rubber chucks. With the pencil mark you can accurately turn the sphere 90 degrees
before tightening into the chucks and clean up the rough ends. Hope it makes sense, first time I have used them.

OU, spheres are pleasant to me. I made of 12 grades of wood, different color. When children roll, wonderful show.

G’day Bob. Well done!! There is something fascinating about Spheres, I guess it is the ultimate in Wood Turning to be able to create a Symmetrical round form…..i wouldn’t know where to start to attempt this, but I will google it and try and get some understanding of where to begin.

I would say that your segmented construction was a complete success as even the joins in the segmenting look symmetrical…there is a soccer ball appearance about them. I would imagine you will explore all kinds of possibilities to use your sphere turning skills in future projects. I will look forward to seeing more spheres.

Kind regards,

Cliff.
