"I was pressing on a bushing using a Harbor Freight 20 ton press with the provided cast arbor plates. I felt the bushing starting to get stiff. about 1/4" left to go I gave one good pull and I heard POW! I felt like I had been punched in the face by a gorilla as the cast arbor plate had just exploded.
