DaBenz, Don't think that I did not TRY to make that lower wrench before I went and bought one

I think that pure physics is the determining factor in needing the lower wrench.... if the top nut friction is more than the friction holding the valve stationary one is going to need to hold that springwasher..

PEH, If the valve turns with the nut then it is not a matter of " a little easier" ...and that proper lower wrench has a little tab on the handle which holds it up at the correct level... I don't have enough hands to hold each nut (two) , the feeler gage (one), and the lower wrench (when needed)(one) ..... that is four hands if the valve is trying to turn... I can manage three operations at once because the feeler gage can be set down and the locking nut dealt with with the same hand while keeping the position of the wrench with the other hand...
