What with a holiday in Iceland, our annual midsummer party and lots of work to do outside, I haven't had much time for turning, let alone blogging.
Nevertheless, I have been working on a centrepiece for the Great Dome Art Fair in Buxton 15th - 17th July. The piece of wood I chose was an exceptionally large plank of silver birch acquired on the trip to Suffolk. Not only was it wide, but it had a fascinating translucent ripple in it - very unusual. It seemed ideal for a platter to hang on the wall.
So I cut a circle out of one of the more interesting sections of the plank, and mounted it in the lathe.
Sorry, my webskills are insufficient to get these in the right order, or delete them!
So the narrative is as follows, and the puzzle is to fit the pictures to the text!
First I roughed out the outside (third row down). I was just getting it nice when I had a dig in. (previous two pictures). Eventually I got it right (previous picture) but then had a problem about how to hold it in the lathe when I reversed it to turn the inside. The plank was only 4 inches thick, and I didn't want to lose any of the depth, so I cut a recess in the base (top RH picture) and used a large contracting chuck to hold it (middle picture top row).
I then reversed the whole thing in the lathe and began turning the inside. I brought up the tailstock to support the centre because of the weight being carried by the spigot in the base.(top left picture)
The deeper I cut the more I exposed an included branch, which wasn't at all obvious in the blank I started with (bottom left).
This is how it looked prior to the final finishing. You can see how the translucent flaring is emerging.
And this is the finished product, 51 cm across.
