This is, in theory, a good way to get a known tension!  But!!...

If your house and garage are built like mine are, the last sentence 
should read  "You then buy a bunch of lumber and rebuild your 
garage."  I tried to lift a small block chevy V-8 off the floor this 
way.  Thank goodness I had the forethought to try to lift it verrrry 
slowly.  The rafter flexed downward as I hauled on the block & 
tackle.  The 500 pound v-8 didn't go up to nearly the extent that the 
rafter came down.  When I started to hear cracking noises, I 
terminated the lift.

I guess what I'm saying is "MY garage's rafters aren't up to a 
reasonable calibration of a Loos gauge."  Beware!
