CVA lathes were top quality English copies of the Monarch 10EE lathes. Google Tony Griffiths Engineering and find CVA on his very long list of lathes and milling machines. I have read them ALL.
Thanks for the info guys. Here is a photo of the chuck. It seems to be very well made indeed. It operated very smoothly, nonetheless, I went ahead and tore it apart to clean and relube. It appears to have been used on a machine that ran coolant. The guts were clean, with no swarf, grease a bit dried. Need to make a new back plate for it. Does anyone know of a cheap source for backplates....even such as reclaimed or recycled material, like rotors from a car? I need it to be 2 1/4" x 8 for a south bend heavy 10.
Ok, so, for the debate on chuck lube. What I went ahead and did was greased the pinions on the back side, as the chuck fits together so tightly, I didn't see how chips could easily migrate into the back side of the scroll where the pinion is. Oiled the scroll, put back together. Does this not seem logical? I know this may open up the great debate, but hey, why not?!
