A lot of work and the cylinder hydraulics don't hold up all that well. Also they are not as stable as the expensive commercial ones. We were jacking up the plane outside for gear checks in Redmond a couple years ago and light winds were really scary. I only use inside the hangar since then and have modified them to make them a little more stable. They are workable and now I'm pretty comfortable with them, but investing in some good ones is not a bad alternative. The aircraft has to go up so high and the jack points are close enough together that light lateral forces will cause things to sway and wobble - makes me pucker sometimes. The episode in the photo was on concrete apron that was not at all flat - that added to the instability and was not a good plan.
