Hello, I’m new... My name is Darren and I’m 27 from England.
Lovely forum you have here, I was lucky to come across is while doing a Google search for vibra sonic tumblers.
I’m aware ultrasonic cleaner works by creating cavitation bubbles within the used liquid, but I’m simply interested if you were apply some grit as well if it would effective? I’m asking this question while reading up on the MT-4 Mini-Sonic Tumbler... which doesn’t state it uses ultrasonic waves but I’m sure I came across a tumbler which does... but I can’t find it again to quote the link here.
I’m new to Lapidary so please forgive my ignorances, I have much to learn.
Thank you for your time.

I don't know the answer to your question. But I would never put grit in a machine not designed to deal with grit. Grit in the wrong place will kill pretty much anything mechanical that moves.

The MiniSonic uses an electromagnetic solenoid that pulls down a plate repeatedly by using a diode in the circuit. I don't know how ultra sonic jewelry cleaners work but welcome to the forum. Most vibe tumblers use a motor with a counterweight attached to the shaft to throw it out of balance. The MiniSonic has no motor so is different in that respect. Gy-Roc mounts the counterweights under the bowl so motor runs balanced but otherwise is pretty standard. All use some kind of suspension springs.

Ultrasonic cleaners work by cavitation: "Non inertial cavitation is the process in which a bubble in a fluid is forced to oscillate in size or shape due to some form of energy input, such as an acoustic field. Such cavitation is often employed in ultrasonic cleaning baths and can also be observed in pumps, propellers, etc." en.wikipedia.org/wiki/CavitationElectromagnetic solenoids operate by inductive coupling of a stator to a coil, i.e. a linear motor. The diode chops the AC and thus produces pulsing alternating on-off coil voltages.
