Shiny gear lever top thingy

So, the story starts with a PM.... Ade, "What's the biggest ball you can turn on your equipment? Could you turn something about the size of a gear knob, for example?"
And it finishes like this....
One bucket o bits. Ade had already made an arbour and drilled/threaded a 31/2" lump of ali bar.
Ade's GREAT BIG..... The threaded end was pre-sized and then it was screwed onto the arbour.
Ade's GREAT BIG..... The radius cuts were started....
Ade's GREAT BIG..... Ade's action shot....
Ade's GREAT BIG..... Mid way...
Ade's GREAT BIG..... A little curve added to the neck.
Ade's GREAT BIG..... Ade's action shot..
Ade's GREAT BIG..... Finished convex cut.
Ade's GREAT BIG..... The little flare turned off and a little bit of blending with some emery. Another Ade's action shot

Ade's GREAT BIG..... Finished!
Ade's GREAT BIG..... And then a pic of it in it's new home....
Ade's GREAT BIG..... Well, that's that one. Been in the 'puter for a few weeks now. Been back at work. No spare time or ridiculous late nights any more
