Most of my problems are getting things a part with out damage which why the 2 lb brass hammer gets a workout. I do consider the hammer expendable.
Once I get things a part enough then its the other pullers and presses that get used. I didn't think the 12 ton press would get that much use but it does. My biggest there is having the right anvils for the press. Most are shop made ones due the type work I need to do.
