He's added a fourth axis

Yeah,but you're using an off the shelf poduct here which is adapted to suit the needs,Irving...I'm talking about making and constucting the parts ourselves to reduce overall cost which has been shown in the two previous vids I posted..

George, thats what life's about making use of what you can, to achieve what you want!! before you can build something on the quality in the vid you need some basic understanding of materials and how to build, and then some form of making the parts, a lathe, a drill press some hand tools and a lot of spare time.

The other thing to bear in mind is ... making parts yourself does not always work out cheaper ... and here speaks the voice of experience

... and then you figure in not only the build time but also the time spent learning how to build the device, how to spec the parts etc..

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.......
