Not that hard to make, a motor & rt. angle speed reducer driving an
eccentric will work. I made one a long time ago for a similar project.

An alternative is making an ultrasonic cleaner. I picked up 4 transducers
that came out of the remains of a cleaner that was at the
scrap yard I take my metal to

The original tank was about 4 x 4 x 4 feet, unfortunately the generator was
not there. On my list is to put a sweep generator/current probe
on the thing and find out its resonate frequency and make a generator.
