I’ve been trying to make a Chinese Puzzle Ball for about 10 years now. Been fascinated by the concept since first finding Woodturning Wizardry by David Springett. Ended up with his tools and tried/failed many times over the years. It was the precision and layout I was having the issue with. Just couldn’t wrap my head around all the equations. Ended up with the full set of tools from Conestoga Works a few years ago and they had some better vids, but again just couldn’t get it. Finally had some clarity the last couple of days and managed to make this. Maple sphere with 7 layers.
