Saw this YT short Wow looks like it produces a nice finish.
Wonder about the roller bearing to ball wearing the internal surface that retains the ball bearing, eventually causing chatter with no way to set the clearance or slight pre load?


Is this a well known lathe procedure ? Might have to try and make one when I get some free time. but looks NEAT
YT build :
