Hi All
I managed to fix my focus issues
I went to a couple of hardware shops, lens and little spacer in hand.
Neither shop could find a suitable ring, so I was disappointed.
I decided to ask my neighbour, a retired engineer, if he knew anywhere that could supply one.
Dave said he could try to make one for me on his lathe and took the little spacer away with him.
He returned about 10 minutes later, he'd printed one on his 3D printer !
It didn't quite fit as the edges were a little rough
He returned 15 minutes later with three and we placed a couple into the lens.
Hey presto it worked ! Well when I say worked, it can close focus OK and focus to infinity too, although infinity is a bit before the infinity marker on the lens barrel. I think I can faff around with the three spaces and the original to get a perfect fit.
Here's a photo of Dave, Sony A6000 and fairly wide open aperture

Good on you Dave!
Champion!
