Flat Lapping

Here is a link to my vibrating lap.  It works on an off centre cam shaft which causes the tray to vibrate.  The final polish, as in the video is done with dry tin oxide on a nylon carpet.  I have found with experimenting that dry tin oxide gives a better and faster polish than using it as a thin, wet slurry.
