The big sphere has finally been set within the sleeping dragon bench. This section has 1 subsection that caps over the sphere during installation. You can see in the images some of the subtle 'orbital' hollowing around the setting of the sphere.
The ring setting of the sphere was quite tricky to get right - numerous times the seating board sections were offered up to the sphere to get the correct radial concave hollowing recess.
next up is the seating section form the right hand end of the back rest section to the mighty knuckle block. Watch this space!
