Thanks for your concern, but I have been working on all kinds of vehicles and aircraft for 50 years - with no accidents yet. I am also ex-military so safety was drilled into my head from day one. I believe that if a project cannot be done safely, then you just do not do it. I am also a quality assurance inspector, so I have witnessed more than my fair share of projects that did not work out very well. If anything, I will probably overbuild this lift just to make sure it does not fail. I will include a mechanical stop to remove the possibility of accidents due to hydraulic failure.
