My machinist told me a non steel backed bushing thats press fitted and final honed to a final wall thickness of 0,030" doesnt make him too conffortable. He advised against it.
He's being too cautious, it's common practice to bore the small end to 1.160" to bush for a 1.094 pin which makes the bushing wall thickness .033". I've run lots of them on the street that way.
Some people run floating pins without a bushing, when doing this it's best to dip the small end in molten tin and then hone to size.
