Episode #194: Ultrasonic Technology with Jeffrey Appling

We are joined by master jeweler Jeffrey Appling to discuss ultrasonic technology in the use of cutting and shaping stone. Jeffrey has been using an ultrasonic drilling and coring machine to cut, drill, and shape even the hardest of stones and jewels with ease. The bit of the machine does not spin, the ultrasonic vibration simply allows the bit to sink into the stone, so it is possible to core out shapes that are more complex than a simple circle, and do it in minutes with relatively little work.

We talk about the machine and how it works, and we talk about the possibility that the ancient Builders may have used something similar to this machine, only probably much larger in many cases, to do some of the astonishing work we see at certain ancient sites.
We also look at some of Jeffrey's jewelry work, and discuss the interesting possibility that an old mission building in California may show signs of containing very old, high tech stonework concealed within rough adobe and cobblestone walls.

Be sure to take a look at Jeffrey's blog and his YouTube Channel to see more of his work, and his research into the possibility of the ancients using ultrasonic technology.

Jeffrey sent us a bunch of images which we discuss on the show. Here they are, more or less in the order we discussed them:


  1. And... this is my brother’s work. He makes sheet latex forms and casts concrete. The pillowiness in his work reminds me of the pillowiness of stonework you talked about. It really is like they were poured into forms. Weird and wonderful.



  3. Excellent interview. Interesting topic and very articulate guest.

  4. Thanks Snake Bros for posting these brilliant photos, I was fascinated to hear, now see, about modern sonic drill work - Jeffrey Appling's work truly is stunning - but, if applied to the work of the Ancient's, mind-boggling: still, how DID they do that?! Thanks, do hope you get more subscribers soon, you deserve millions! Gina
