The man who once owned “Contempo Lapidary” is now selling ultrasonic
drills. As I remember the base price for one model was abot $1800. He
has models that cost more; depending on the power of the unit. He has
been at Tucson across from Alpha Supplies the last couple of years.
There are others who post to Orchid that really know ultrasonics.
I’ve only been toying with the idea of getting one.
The Japanese ultrasonics must be amazing machines at that price, but
they produce a great product.
