Poor Robo...he's obviously put a lot of time and effort into building this. I've had a car drop onto me many years ago...luckily with nothing more than bad bruising, so I'm VERY wary of going under a car. If you are happy with the lift and the jacks are well secured to both floor and wall and you are not lifting too high, I'd stick wooden trestles under the car once up and take the strain off the jacks. The trestles are good enough for the factory.
