    The air jack is a neat idea; though I'd be nervous about deflection once a wheel is removed. Seems to lack having some type of rubber for traction, or locator for seam of rocker panel; a feature of EVERY jack and jack-stand.

    Yes a thick hard rubber pad mounted to the top of the air jack would seem to be a much desired safety feature, if for nothing else to help protect the underbody of the car's rocker panel.. Not all cars still retain a pinch-well connecting the rocker panel to the floor pan any more, a feature that for a while had specific jacking locations formed right into the car's body, which was a place where rust would begin as well.
    back in the day bumper jacks Remember those? Better yet remember when the front and rear bumper was the most striking feature of a car? Bumper jacks used to have a formed removable piece that was molded to fit the bumper's shape. Then manufactures began to provide a divot in the bottom of the bumper as a jacking location. Eventually a slot was made into the bumpers for the jack to lock into. early German and Japanese imports came up with adding a receiving socket. Later on just a spot for a jack to actually pinch the pinch-well. The advent of radial tires was the beginning of the end for carrying spare tires and jacks in the vehicles as well.

    Pinch weld! Couldn't name that for beans last night. Coolest thing about vocabulary though, associated terminology will still convey the message.
    I do recall, when bumpers were tangible, not only decorative; but substantial enough for each outside corner notched to locate aforementioned jack!
    Last few weeks, worked on unpacked crates in the building. All marked for content, just hadn't needed them yet. One item that'll repurpose nicely, one of those jack attachments, a hook that connects via 3 links of flat chain to jack mechanism proper. They appeared with those deeply wrapped under bumpers, better than a flat horn could dream of.
    I won't tax it beyond a couple thousand pounds; not for actual lifting, but a toe-jack that'll slide into pry slot or under a machine base. Plenty high for low profile skates or preferred Egyptian rollers.

    Very dangerous. Pressure does not equal rigidity or stiffness! If only used as shown, with 3 other wheels on the ground stabilizing the load, it might be useful. There is no stabilizing mechanism and if lifting a load not stabilized in some other manner it could easily buckle and tip over!

    You ever squeeze watermelon seeds between your fingers to shoot them at you brother or sister? That is what you have there if conditions are right. If the car tips or starts to slide off, don't be standing in the line of fire!!!
