Waterjet Coasters (2022)
Coasters
Motivation:
These were a father’s day present.
Description:
These were cut from marble on a small water jet. They also have small felt feet on the bottom so they don’t scratch tables. I didn’t use backing, but probably would if I did it again. The gear was an attempt at using the etching feature on the water jet with some of the scraps.
Lessons Learned:
The stress concentrations on the marble are on the darker lines because when the water jet pierced in those locations, there were more flaws.
Attempted etching. It pierced the marble when the water jet slowed down for tighter curves.
