How to make a ultrasonic lapping machine?

Hi everyone, I´m interested in making my own ultrasonic lapping
machine
and would like to know if there´s someone with diagrams and/or
knowledge to build one of these. I´ve tested using small motors (the
ones used in a power sanding machine" but it didn´t make much. I hope
you can help me out building this machine. By the way if this machine
works, I will send a copy to the person that sends me the winning
diagrams. Well, I thank you all for your attention. Best regards.
