Eeek! Probably fair given the work, but prety steep just to eat you fish & chips off!
It also states ".... Astonishingly it remains truly circular in the process..." I can't believe that is strictly true. If the rim is circular at the smaller size, the radius of curvature at the outer edge cannot still be circular when moved outwards. I think the infil panels are 'appropriately' curved to match up, but the result at the larger size cannot be precisely a circle - not in engineering terms anyway.
Pretty looking bit of furniture mind for all that
