.... well that was disappointing.
The Rev Counter for the lathe refuses to work correctly.
Most likely culprit was/is EMI causing the detected transducer pulses to get swamped so there was no clean signal.
I tried putting the whole transducer and its cable tail in a shielding braid earthed at one end but it has made no difference.
I have run out of ideas and the only remaining option appears to be to put the whole VFD inside a faraday cage/tin box.
This might work but as it needs to be air-cooled it may mean buying some perforated sheet to make a box from.
I wonder if shoving a biscuit tin over the VFD would be a good temporary test? Hmmmmm.......

You must have a particularly bad unit. As you know I have two and neither give problems. I have a completely separate unit I use for testing that you could borrow to see if it is the vfd..... well that was disappointing.

Switch to the old fashioned way. And use your judgment and work in progress if it don't work alter the speed ?.... well that was disappointing.

That is very kind Brian, thank you!
I have ordered some ferrite chokes to put around the power and signal cables as a next step.
Barring this I will then rewire the "control box to VFD power cable" with a longer section of cable and place the VFD further away (aka temporarily lay it on the floor outside the garage and lower the shutter); and see if increased physical separation helps (it should).
The VFD is a "cheapie" for sure it is an XSY-AT1 (I think it was only £69 from Banggood) but it works great from a motor driving perspective, it may just be "noisy" electrically. We shall see. A disappointing setback, but not a disaster.

I know its different but I do a lot of wood turning on a lathe and speed is dictated by density of wood the pressure of your tools and how fast you move them into the wood and the Finnish you require one glove don't fit all it has taken many years of experiences and trial and error even % of moisture in wood has a big impact also types of wood cherry ash oak elm even orientation of the grain and knots and sharpness of your gouges this type of work is not dictated by grafts or mathematical calculations its experience and to be enjoyed

I’m quite interested in what else might be available from ‘banggood’The VFD is a "cheapie" for sure it is an XSY-AT1 (I think it was only £69 from Banggood) but it works great from a motor driving perspective, it may just be "noisy" electrically.

Well blow me down!
I have only done it once, under the supervision of my experienced ex s-i-l, turning a new pine stretcher to replace one the dog chewed through. Never thought about any of this, just went for it and got it right first time.
"Turned" out fine!
Maybe for once I learned a knack real quick.

But could you duplicate itWell blow me down!

I was trying to duplicate the exisitng one! I didn't do bad considering I was doing it by eye, it was like a twin ogee in the middle if you see what I mean. One side was better than tother.But could you duplicate it
But could I do it over and over again?
Who knows? Maybe it was beginner's luck or it was OK and would get better with practice!! I didn't make a template or anything. Just did it by eye and held the other one up to it as I went.

They may do a range of "GoodBang's" I'm not sure.I’m quite interested in what else might be available from ‘banggood’

Probably 'cos your ex s-i-l set it all up for you and all you had to do was concentrate on using the gouge.Well blow me down!

Maybe. As far as I remember he stuck a bit of wood in the chuck and made sure it was held in place by the bit at the other end, Don't know the technical term. He fished out a tool and showed me how to rest it on a sort of bar thing and move it in and along.Probably 'cos your ex s-i-l set it all up for you and all you had to do was concentrate on using the gouge.
This was all about 30 years ago, so memory is a bit hazy. But I was very happy with it and once he thought I'd got the general idea he went off and did something else.

These are the sort of things I used to make.
