Until the pin sheers, which I have done.  Then the whole thing crashes down 
instantly.

They're cast aluminum, which snaps with no warning and no bending.

The base is small, by anyones measure.  Very unstable.

The base is capable of rolling.  Check out the history of that disasterous 
round based stand Snap-On came up with a few years back.  Had the neat habit 
of rolling with the car on them.
