Hi there, Its nice to see a millgrav in good hands there. I worked at Newing-Hall as a fitter for 20 years and in that time I built or worked on just about every millgrav that we made. Its 10 years since the company went under but I think Pantograph Services of Leeds took over the handling of Newing-Halls affairs. I like the new spindle arrangment you have there, the large aluminium pulley on the original motor could sometimes cause trouble with vibration. The millgrav was one of my favourite machines because it did away with the old pantograph which could sometimes be difficult to set up and it was so easy to knock it out of square meaning a service call out to reset it. There were a couple of variations of the millgrav in that one had a solid aluminium plate holding the Y carriage and that had the slots for the ball blocks permanently machined at 90 deg to one another. The other had two aluminium plates on a spigot that allowed the two to swivel. We then had to manually set the plates at 90 deg to each other and dowel them with tapered pins. These machines were sold all over the world, The Jet Propulsion Lab USA (NASA) had one, Australia, South Africa, UK. Anyway, you will have to post some video footage of the machine working when its all up and running.
