Here is how to make family and customers happy with a few quid and little effort. SPOILER ALERT!! It gets addictive once you get the hang of it! ... Check my other project for the HD photo version.
Choose your preferred Tumbler, remove all the labels and eventual hanging parts attached.
Clamp the bottle on the Rotary RA2 (or lay it within the rollers).
Use my settings, but allow yourself to play around it if you prefer Etching rather than carving.
And fire up the Laser!!
Grab windows cleaner and soft cloth to gently wipe the surface!
DON'T RUB IT!!
And job's done!
