Most importantly.

Does anyone know how to make an ultrasonic cleaner?
Is it just vibration, or does the vibrating motor need to be tuned to a specific frequency.

If I use an old hand drill with a concentric hub on it, and a variable speed power supply, can I get it to the correct frequency?

If I can, how will I know I am at the correct frequency?

Which is why ultrasonics can be good- no sounds that we can hear.
