Hi,
First I'm going to warn you that I don't know a thing about lathes / CNC...
Take the thing on this page:
http://www.japantrendshop.com/ice-ball-mold-for-perfect-ice-spheres-p-244.html
While the small version is fairly cheap ($216) the next smallest is way more expensive ($1393).
Could someone explain to me if there is any technical reason for this (material cost? production time? complications to create a sphere that big? size?). It's just a big block of aluminium with a sphere cut out :whistling:
How much do you recon it would cost me if I wanted someone to create a similar device for me? (for a 55mm sphere), around the same or could I get off cheaper?
Thanks,
Andreas
