Thanks for your help guys much appriciated.
I know it would be easier and cheaper to buy a used cnc lathe, but i like the fact that the caz has a short headstock, like i said in my first post, i,ll want to get to the rear of the spindle to adjust a spider while clocking a barrel in, also the caz has a hydraulic varispeed, with a high and a low gear. The more i look into retrofitting this the easier it looks to do. As for a toolchanger, i like what hood has on his, and will want something similar, i think 'duplimatic' make one, aswell as others ive seen.
