well, it's certainly been an interesting discussion and brought back days of 
surveying calculations with a 4 function calculator and a pocket trig 
table.... but here's the correct answer...

I finally got the time to dig out my hoist and do some measurements (actual 
not theoretical))

one inch of lift at the jack point from horizontal produced 3.5 inches of 
lift at the hook end

then next inch of lift produced 3.75" of hook lift. and it varied between 
those two numbers up to about 10 inches at the jack point.

I wasn't looking for really precision answers and since angles and such do 
change over the range of motion that calculation would be complicated for 
sure... basically I was looking for an approximation and I got it after 
nearly emptying my shed out into the yard to locate my hoist... but another 
benefit of this exercise (for me anyway) was that I found a hydraulic pump I 
had been looking for and found a nice field mice nest that has been 
eliminated.

don't know why the actual didn't jive more with the theoreticals ???  maybe 
we didn't consider moon phases...

thanks for all the effort and lively discussion..


now the next question... how does stuff get to the back of a huge pile that 
just last year was at the front of that same pile, and in the way, when 
searching for something else... now I KNOW that's got moon phases all over 
it !
later
