The Tube Setting is similar to the Flush stone setting. I am using a modified round bur that will make a seat for the stone to sit.
You can see where the groove for the stone is being cut.
This "Half-Round" is what I created many decades ago and it works so very well.
With the Reciprocating Hammer I 'moved' the metal down on the edge of the Girdle of the stone. I never hit the metal hard.
There appears that the rim of the metal has now a flange beyond the rim. This has to be removed as soon as possible!!
You'll notice that the hammer anvil has not touched the stone. This what I expected, I can even set Genuine Emeralds in this Tube technique.
A gentle filing has removed that 'flange' around the rim. NICE?
I placed the Tube securely on my shellac stick, as I didn't want any movement while Bright-Cutting the Bezel rim.
I didn't break off the Tube from the shellac stick. I just heated the surrounded surface and it came off without any effort.
With the Reciprocating Hammer I 'moved' the metal down on the edge of the Girdle of the stone. I never hit the metal hard.
The tip of the Hammer Anvil is held at a 45degree angle.
I placed the Tube securely on my shellac stick, as I didn't want any movement while Bright-Cutting the Bezel rim.
This Bright-Cutting is an exercise in keeping the graver & Tube secure in this delicate time.
If I used my ring clamp, the Tube might have moved and come loose.
Having the Tube melted into the shellac was a wise decision, as I wanted the Tube Setting to be set without any problems.
