Ignoring the cost of the stepper/control/chuck which are roughly common, the aluminium to construct that axis would be about £30, the steel spindle about another £15, the bearings about £15 and the pulleys/belt about £18 and machine screws etc about £10... you might do marginally better, but by my calculations the parts alone are £88, my rotary table was £40, the conversion parts about £10; it took me a lot less time to convert and only needed the lathe, no CNC milling machine....

Sometimes cheaper is illusionary.......
