Proof of ancient ultrasonic machining of Rock
Advanced ancient stone machining in New Zealand
5-point star shaped drill holes found in rock measuring over 1” in diameter are ancient and not made within the last 9,000 years.
The above large star shaped drill hole in rock found by Mike Crump in New Zealand measures over 6” in diameter and is proof of ultrasonic machining in ancient times. We cannot recreate this hole today without using ultrasonic technology and a large shaped metal tube.
When ultrasonic drilling with a star shaped tube, the hole takes on the same shape as the tube. A 5-point star shaped tube will ultrasonically create a 5-point star shaped hole in rock.
When a star hole is first cut, the hole appears to be perfectly shaped with all minerals ground down evenly and smooth.
Star holes when first cut into rock have a SG-1 (Excellent) grade because there is no weathering and erosion to wear them down (fresh cut). The above 5-point star holes were made within the last 8 years and show the identical marks seen in Ancient star holes found worldwide.
The below 5-point star hole photographed in Scotland is a fine example of star hole machining using ultrasonics and a shaped metal tube. It appears to be fresh cut.
Ancient star holes that have a high grade of SG-1 or SG-2 are usually found underground and hidden from long term weathering. Once an ancient star hole is dug up and brought to the surface, it holds its original clean and crisp star shape as if machined yesterday.
The large 5-point star shaped drill hole in New Zealand shows the magnitude of ancient machining.
Ultrasonically created star holes show evenly spaced internal lobes and all minerals in the rock are machined smoothly.
The above (left) star hole from New Zealand was created with a large star shaped tube.
With Ultrasonic drilling having a feed rate 400 times greater than today’s diamond core drills, this giant star hole was created fast and in one continuous motion forward.
