Project Information

Fun with new shapes!

I have turned a ball shape on a christmas ornament. That was easy compared to these. With the posts for the upper and lower finials you have something to hold onto. Turning a ball, without having any tool marks where you held it ( i don't have a vacuum chuck) Is difficult, to say the least.

Start out with it between centers or in a chuck. A longer piece should be used. Turn to a ball shape with the mount marks in the "extra" pieces at the ends of the longer blank,Cut blank down as much as possible to shape.

Now, Remove from lathe and turn 90deg and remount! DO NOT USE THE TOOLS TO HOLD THE WOOD!!!!
You must first devise a clamping system to hold the ball without touching the all ready turned areas.

I used a wood cup mounted in the chuck and another piece mounted on the tail stock.

Once mounted, Turn the wood again to the desired size.This will clean off any excess left on the shape.
Repeat the procces for each step of sanding and finishing.

By turning the wood 3 or 4 times before going to the next grade of sandpaper you will get a more uniform roundness to it.

The first ball is only 2 and 3/8 inch Diam, But it is within 1/64inch of being truly round Only .015 from being a true sphere.

Claro Walnut, with Turquoise inlay.


Second ball is Jarra Burl, 2 and 3/4 diam within 1/64inch of being truly round.

Some of these could pass as planets.

Have you thought about making a model solar system? What wood could you use for the sun?

I like the crevasses in some of them it makes the look very organic as opposed to monolithic!

That is quite some technique you developed for making these!

Great job. I like the turquoise inlay. I have been wanting to try some of the inlaying. Where do you get the turquoise?

Very nice and you are right, it is very hard to make something completely round…strange when you think about it, it should be easy but it is not

I like them both but I love that walnut one!
I guess next you'll be making bowling balls lol!

Awesome balls! Great technique and control turning them. Like the walnut with turquoise inlay. Great and unique decorative piece.

Thanks for all the great comments everyone. These were a lot of fun and a challenge to make.

oldnovice, I could do a set of planets, sound interesting. The sun could be OSAGE ORANGE. It has a great yellow/orange color to it. I think the earth would be the biggest challenge. hat wood for BLUE and GREEN?

Idl, They sell turquise around here in Arizona in several places. I got mine from a yard sale of another wood worker. (he had to retire after a stroke). Check on line and craft stores.

Karson, A bit small for bowling, and my lathe is only a JET 12×20. Would tax it for a bowling ball. haha

I do plan on making several more of these. They will look great in a turned wood bowl on the TV stand. Have to keep trying different wood for a more full range of colors and sizes.

Thanks again for the comments.

Scrappy, those look really cool and incredibly difficult.

I've no turning experience, but my class just received a lathe from another school. I've been asked by the local civil war re-enactors to turn some cannon balls and another shell used by the local battery, not to fire, just for discusion and exposition. If you could give me some resources that would provide some guidance it would be greatly appreciated. Never having turned, I think I understand, but could use WAY more explanation. If you would prefer to pm that would be fine. Hoping this may get my students not only interested in the project, but working with the history.

Thanks, Tom
