its difficult to see on that picture if its cnc turned to an extremely fine finish or if its polished with emery cloth

but I would guess this was an part of the cnc education

but its still an extremely high quality build and shows what an highly skilled craftsman can accomplish
doesnt matter if its cnc turned or made manualy , its just a lot more work to do it in an manual lathe and takes lots and lots of more time .
on the other hand I would guess that the programming wouldnt be easy to make either if its made in an cnc machine , but I dont have any experiance from such things .
but if I had there would be another problem , to get $100 000 to buy an cnc lathe and mill

so Im happy that I dont know howe to do it
