Handcrafted jobs are one of the most humble and admirable jobs. Sometimes the final product it's not perfect but it's unique.
The same happens on Peter Bellerby's workshop where he and his team design and paint these amazing globes. When making them they need one hell of a steady hand because even the tiniest deviation is multiplied by a factor of Pi. Which means that an error of 0.1 mm translates to a 2.4 mm gap. Although, their globes are more accurate than thoses made on a machine!
