Making the cut with a worm-less Shamir.

Ultrasonic drilling with a curved tool can reach hard to reach areas for removal of unwanted aggregate.

I was introduced to the term “Shamir” by the “Brothers of the Serpent” podcast. The Shamir (many different spellings) came from the ancient times and was said to break hard materials. It was said to be a worm of some sort.

Ultrasonically drilling creates round holes and scoop marks (technosignatures).

(Below left) The unfinished obelisk in Egypt shows straight step-like scoops. We discussed this topic on the “Brothers of the Serpent” podcast, episode 194.

Straight tubes used ultrasonically can make straight scoops marks only and not curved scoops.

(Above right) Scoop removal in hard-to-reach areas and in a curvature that cannot be created with a straight tube. A shovel-like scoop tool is needed.

Behold the wormless Shamir. A Bent brass tube on metal horn.

(Below) Using 4mm Brass tubing, I bent the tube and crimped the end like a shovel. The curved brass tube is soldered to the metal horn.

The metal horn with curved tool attached is screwed onto the ultrasonic machine (transducer creating high vibration).

(below) The vibration created by the ultrasonic machine flows down the horn and along the curved tube. As the vibrating tube touches the Sandstone rock with abrasive slurry flowing over, a 1mm deep indentation is made in 20 seconds. The tool violently vibrates, and the silicon carbide abrasive makes the grinding cut.

The shape of the brass tool’s end dictates the shape of hole created. (above right) The rectangular shaped end of the shovel-like tube created the same shaped hole.

I cut off more of the brass tube (centimeter) to allow better access for abraisive slurry to run down the tube with ease, enhancing the cutting action.

The vibration runs through the curved brass tool and easily cuts 2.5mm deep into the sandstone is less than 25 seconds.

(Below) Round tubes make round holes and straight scoops.

The shape of the tool’s end will determine the shape of the indentation. This includes square, triangle, and star shapes.

Using Ultrasonic technology of our ancient ancestors, I now can create geometric holes or patterns in stone. The technology is no longer lost, its being applied to my jewelry and to my artistic jade sculptures.

Square holes, Triangle holes, and yes… my signature star holes are all created using this ancient technology. I have found that the ancient technologies used in the past (magic) had a lot to do with the science of Nature.

This ancient ultrasonic technology can be used on the toughest rock, Nephrite Jade, and on hard materials under the hardness of 9.2 on the MOHs scale when using silicon carbide powder for grinding. Diamond powder will grind anything under the hardness 10.

Some of the most beautiful wave-like textured and pattered Nephrite Jade is found in California. Below are some examples of ultrasonically carved shapes (drill holes) penetrating through tough California Jade.
