Lathe roller centering tool

[rendoman]

Hi!I
I decided to build a centering tool for lathe, after seeing some project on this forum .
The bearing is a 20x52x12mm unit, used in 50cc 2 stroke engine for Piaggio scooter (long and short arm models), I have also some spares with lateral shield.


The tool shank is a hex bar, I chose this profile because it's easy to be tightened on the lathe. I machined a round part for the bearing and a little step to help removal (if needed). I milled one side in order to keep the tool near the holder.
