Newman, I did not understand your comment -- could you clarify? And Bumpy, I tried those "oil derrick" things (I had a couple sitting in the garage), but the base was a little too narrow, and it rocked a bit. The tripod thing distributes the load over a wider area, and the angle of the legs means that the "force vectors" from the jacks run straight down the legs, instead of coming across the top of a narrow "derrick." (As you can see, I did poorly in high school physics -- not sure if this is really an example of vectors, but how often does one get to use that word in a sentence??)
