Has anyone had any experience with micro-polished parts? Maybe someone has attempted a DIY solution. Look here for reference https://www.cryoheat.com/micropolishing-deburring/ Peter.

Ah yes. I recall reading your post now. Anyone know of someone in Melbourne that does this? I would be interested in understanding a bit more about the process to see if it is feasible to set up in a garage. The videos show a vibratory setup, but I am thinking that maybe a tumbler with the correct media might do the job.
