For me: bushings designed for the purpose from penturnersproducts..

I also purchased my 60* dead center & 60* live center from John.

I use calipers and never trust the bushings. Bushings are usually sanded down or touched with the chisel. For a long time, many people considered the bushings as a disposable item because it was constantly being worn down. And as it wore down, then sizing became a problem. So, if calipers are used, you never have to depend on the bushings for sizing.

One reason for calipers is this: the nib end, the center band and the clip end - all vary .001 or even .002 or more from the bushings. I always turn my blanks to the sizing on the CB, nib or clip end. Never to the bushing. Actually I turn it down .003 or .004 below and build that back up with CA for a more precision fit.
