great vdo, thanks for your contributions.
Any chance you could give us a bit more HowTo detail on those 1" screw lifts, show them in action?
Not on this project anymore I guess, no rush, but maybe next time you use them?
For my use case, regular lifting and lowering a roof loaded with maybe 800#
I'm hoping to keep the four "screw pillars" inside the living space, and apply an air or electric power drill from the middle rather than top or bottom.
