The beam is part of a sash clamp I used for making window frames many
years ago.
I set it in the nearest hole to give me the weight I required and
adjusted the rest with the much under used weights from my barbell, then
carefully lowered the jack and kept my fingers crossed.
Im sure a Man of your ability can do the maths for whatever you have
available.
The check is 60% of 700 lbs for 3 minutes I think, but read the document.
Incidentally, the breaking strain of a well made Nicopress is about 1.5
times the minimum breaking strain of the cable hence I only used one on
the ends of my cables.
I was hoping to be flying by mid year until my neighbour conned me into
helping lay 160 meters of concrete during our 30 Degree, 70% humidity
days, which has slowed build progress a couple of Months.
