Sleeving a cylinder pros/cons

Yes,

But how would you know if it's done properly.

Not all Boring Bars are the same, as well as the operator.

Do you know the difference between an 'old' Van Norman Boring Bar,
a Kwik-Way Boring Bar and a Rottler Boring Bar.



'Cause he's too far to bring it to you? :D

All my work block work is done on a Rottler F86A, by guys I've been dealing with for almost 20 years. The same machine does about 150 import blocks a year with interlocking sleeves. That's how I know it's done right.
