Timeline

First, create a V-cut with an angle on the ring \[00:30].
The V should be knife-edged \[00:42].

Start at a low power setting and gradually increase it until you achieve the desired action \[00:50].
If it sounds "splatty", it's too hot, so decrease the power \[01:12].

Tack the ring to make it hands-free \[01:29].
If you're not happy with the position, you can break it apart and start again \[01:37].

Infill the groove with matching gold, either using laser wire or gold from the ring itself \[01:44].
Offer the laser wire into the groove and fire the first shot just in front of the wire \[02:12].
Continue with additional shots, ensuring the gold is fully melted into the groove to avoid pockets \[02:28].

Adjust the power as needed, especially if the finish changes or carbon is present \[02:58].

Fill the groove without worrying about tidiness at this stage \[03:30].

Increase the spot size to tidy up and manipulate the material \[03:53].
Superficially work on the inside of the ring \[04:20].

Cutting a V and infilling makes the ring strong because you're printing material from left and right, melting from base to top \[05:03].
