Sleeving a cylinder pros/cons
Boring for Sleeves
Usually a standard type Portable Boring Bar, which is anchored on the Engine
Block is not the best way to go.
A better process, is to have the cylinder bored out with a Boring Bar mounted on
the Boring Bar Bench.
We use the Rottler F2VB, which is the 'industry' work-horse boring bar.
Not that a Portable Boring Bar {ie; Kwik-Way #FN} can't do the job, but
you're taking out a lot of meat with '3' cuts at .040".
