  The process is called Fescalising.

  its always bugged me that polishing or sanding a surface always involves removing the material in high spots, its really satisfying to see a tool that works my mushing the high spots into the low, it feels right in a way

  Oh yeah - add a big ink reservoir and you've just created the largest ball point pen ever!   :D

  Switching tool and object for slot milling was the interesting part for me :)

  This is incredible. I was confused at first but after watching this it makes perfect sense

  Nice Ball Bearing Burnisher.  I used something like this in my old job to smoothen and compress the surface of the internal bore of a cylinder to make it a better surface for hydraulic seals.

  When pressing bearings, support the inner ring!

  Very cool approach. The ball leaves a surprisingly nice surface. Definitely trying this on my lathe.

  This is actually roller burnishing.

  Great idea, I haven’t seen this done before. &nbsp;Tempted to make one myself!<br><br>Looks like your tail stock is a bit out of alignment or that big drill is a bit bent. &nbsp;It really flexes when it centers in the hole.

  Also wondering if you could skip the solo &nbsp;ball and just lightly radius the outer race of a bearing on a bench grinder or diamond grinder then just mount that little curved monster on the end of your tool and eliminate the ball. I wonder if they make a small, sealed, tapered roller bearing that would resist the lateral load better. Just thinking out loud.
