Yesterday I rough turned four large blackwood bowls.
Today, had high hopes of repeating the task.
It was not to be. A lapse in concentration meant that the foot/tennon of bowl number 1 for the day was turned with no allowance for future shrinkage with the particular chuck jaw set intended for the job. The foot diameter is 180mm and any smaller might draw criticism from folk (other turners) who are banana sensitive:wink:.
You can see in the picture that the chuck is not far from being fully closed on the foot.
447537
So decided to finish turn this number green.
Diameter of bowl is 510mm and height is 120mm.
Wall thickness is 16mm.
Was surprised how relatively easy the outside sanded with minimal clogging of paper.
Inside was a different story.

You can see on the underside the chuck jaws have caused a bit of discolouration on the foot due to wanting to rust with the wet timber. That will have to be hand sanded out later. Or not.
447539
The vertical lines on the lower left of the above picture is where the centrifugal force has cause moisture to work its way out while turning the inside of the bowl. Will see how it looks in a day or two and if need be lightly sand again on lathe.
Now just have to hope it behaves itself drying out.
There is nice grain in it, photo does not really do it justice. It should look sweet with a bit of lacquer if it dries ok.

Finally a picture of the queue jumper with the rough turned ones from yesterday.
