Really- WOW - I wore out my first Rockchucker in about 1980, then the second in the mide 90's. I guess 20 years is all I get out of a press. I didn't even think of sending (expensive) them back to be re-built as the casting was worn oval by the ram. I merely threw them away. I currently have 2 Hornady presses, a Lyman Crusher which I really like and an arbor press for my .17 centerfires. They're all great.
