It's good fun and a steep learning curve. Not too difficult and sometimes difficult to imagine what the inside will look like when it isn't on the outside?

This is a heart shape

And finished up looking quite nice IMHO

A 3 piece

I didn't like the blue candle so I made a red one.

Then I went totally mad a did an 8 piece. That nearly drove me up the wall!

That will be a one off!

This looks cool! I've never done an inside out turning.

That’s really cool. I’ve done some eccentric turning but the inside-out turning is another level. I think it’s going to be hard for me to visualize!

Not so difficult if you stick to 2 bits for a while and the heart isn't bad. A little difficult to get up in to the top and get your head around that you need to go quite deep.

If you look at the first photo you can see that and there is a cart load of youtube on it.

Try, the worst you get is some more firewood. Oh and when you flip the blank inside out glue the halves together with some card between them. It makes them easier to split. I always wrap some gaffer tape around the ends for the belt and braces feeling, with Steb type centers at each end.

You can do lovely single stem flower vases too

They use such small lumps of our wood. After all, just remember it ain't like money, it don't grow on trees you know

I had some Oak and tried a 4 piece but the wood broke pretty badly. How thin would you consider enough? I still had about 3/8" thick in the fattest area, I thought that was enough.

That's difficult to guess at that Pellikan? The hearts above, left is oak and right is ?? and fairly woodworm munched and they both obviously survives. I use Steb centres at both ends as they don't put any pressurs of a point on either end. These are they and obviously again a live Steb at the tail stock. A bit expensive, but I use them all the time for spindle turning.

The original Stebcentre is a lathe drive centre with several unique features.It uses razor sharp serrated teeth to grip the work piece, without the need for pre-marking the wood with the drive prior to putting it onto the lathe.The greatest benefit the...

Also, too much pressure from the tail stock may have been the problem? Just a thought, you said "I still had about 3/8" thick in the fattest area, I thought that was enough." Did you mean the fattest or thinnest? Because if you went thinner then it would have made both my points even more likely?

very interesting. i've probably seen that before and wonder how the heck it was done.
thanks

Thanks for the reply. I use a steb at the head and a cup shaped live center at the tail.

It's difficult to describe but here goes. I was trying to make a Christmas ornament with 4 pieces. I turned the inside part and that went fine. After I flipped the wood around and started on the outside the individual spokes of the ornament became roughly football shaped in cross section. The thickness in the center of the football was about 3/8" and it tapered to points.
Possibly I just had a catch. At the time the wood broke apart it was firmly glued together on the ends so it didn't come apart, the wood broke. I thought maybe the oak wasn't a good wood for the project, having open grain led to less stability.
If I'm going to try again maybe a denser wood or more speed or thicker spokes. It was my first, and so far last, try. I do want to try again, thus the question. Trying to get a better sense of what went wrong.
