Then you are at the wrong place, the original studs are swaged (like rivited), just pushing the studs out can damage the hub and drum, the swaged area needs to be cut ---
there is a small arbor for some modern machines that can be used ---or find someone with old barrett, that machine has adapters that fit in the wheel bearing, don't even have to remove the seal,
drums should be turned after mounted on the hub
