I love bottle jacks. We're disassembling a deck to prepare for adding a room to the house & used an ancient bottle jack to separate boards where deck screws broke etc. Thinking back, I don't recall ever using one to lift a car, but constantly use one to lift heavy parts into place, pry things apart, etc. The one I have has been with me forever.

No big deal - just thought I'd mention it.

Hard to get one under an LBC.

Used a few of my grandfather's to push up a 1928 frame house to re-enforce the flooring. Great tools!!! "Jaws of Life" stuff is impressive, too.

My father was with the railroad and had a rail jack - not sure how many tons but we lifted some pretty impressive stuff over the years

Too bad Archimedes never paired oil with enclosed systems!!!

Just used a bottle jack whilst putting the rear spring on the Corvette......28 of those 12"x12"x2" concrete pavers stacked on the rear crossmembers & a bottle jack under each end of the spring allowed me to jack it up enough to hook it to the trailing arms.
