Step 10Hollowing the ring
The object of this process is to lighten the weight of the ring by cutting a channel underneath the stone seats thus hollowing down the thickness of the top of the ring.
It is one of the hardest parts of this project so take your time.
You should aim to thin the side walls to no less than 1.2mm, and the top depth to no less than 2mm.
Turn the ring so that the top of the seats face downwards and using the scribes trace a 1.2mm wall around the inside of the ring underneath them.
Use the flexshaft with the detailer's burs to carefully cut the channel between the scribed lines.
Tidy the channel using sharp edged shaped and curved wax working tools.
Use the degree gauge to measure the thickness of the walls, and hold the piece up to the light to check for uniform thickness (the lighter the areas the thinner the wax).
Feather the channel out to the mid point of the ring band to give a smooth transition into the rest of the band.
