I have one of these (cheap import) air-hydraulic jacks that I picked up in almost unused condition from an estate sale with a bunch of other stuff a few years ago. Paid $25-30, I forget. I've never owned one before, and have never used one. The hydraulic press in my shop is one I home-built from 6" channel a good forty years ago, using a Sears 12-ton bottle jack. I have never plumbed a guage into this manual jack. I have thought of swapping-in the new air-hydraulic jack, and plumbing-in a guage so I have some idea where I'm at when turning the valve on the input air. The thing Iike about my manual jack is that I can sort of "guage" the degree of press by how hard it is to push the handle. But as I think of it, the new jack can also be used manually . . . .
What uses, if any, have you guys found that these air-hydraulic jacks do particularly well? I rarely use bottle jacks under cars, since I have a good selection of swing-arm car jacks. As of now, this air-hydraulic jack just gathers dust. Of course, as with all Chinese tools, you have to hope you are lucky and get an example that doesn't [email protected]
It looks about like this one, maybe same thing:
