Thanks very much Lugnutz.
The four-post lift is inherently stable - after the four legs are held together with the side rails.
I/we will be extremely careful.
I will have one helper at all times.
At the final lift, I will have 3 helpers.
One neighbor is an EMT/fireman.
All four of us have done construction/roofing.
No beer will be imbibed until the lift is bolted together.
