I've had good success using an old driving flange with 4 point contact
and a driver of some sort on the inverted cylinder liners, with the
block on the bench. I pull the block over the edge and knock the
sleeves into a trash pail (always full in my garage). I worried about
damaging the bottom edge, but I've done 8 this way with no damage
whatsoever.
