<VV> Unsafe at NO speed (elevating your Corvair)

[Chris Mann]

Although someday I would like to get a professional hoist; right now, I thought I would ask all of you how to elevate or jack up your cars with you run-of-the mill floor jacks, and feel safe about it.

I seem to scratch my head a bit when I jack up the car at the proper points and then attempt to switch to a tripod jack so that I may move on to the next corner. The clearance between the floor jack at tripod jack is always so tight, especially when working in the rear of the car at aiming for that "right spot".
The front is easier to deal with because you can jack on the crossmember and land to jacks on either side. Then again, maybe I shouldn't jack there?

And to add to all of this, what about the road racers, and more mobile (emergency) jacking situations, how to you handle 'on-the-spot' or 'in-the field' jacking?
