Plumbers may not be actually human; in view of constrained areas they demonstrate entrance to and chose to work. There are a few companies that cater to the rest of us, constructing tools to operate where conventional items just won't.
Friday last; faucet replacement. Predicament was dependable 35 yr old faucet/basin wrench impeded by undersink hardware and lack of universal joints in elbow/ shoulder. This model 1017 had four adjustments, 10" to 17" in 2 5/16" increments. Holes receive spring loaded detent pin. Neither 12 5/16" or 14 5/8" lengths allowed the jaws to reach AND loosen faucet fittings.
Maintain same spacing offset by half, drill 3 additional holes opposite face of 4 original locations.
Used original hole to duplicate centerline, flipped the sleeve 180 degrees, centerpunch and drill as described. New effective intervals are 1 5/32". Didn't take 15 minutes, and saved extensive anger-tinged vocabulary for later.
Plumbing itself and it's respective tools are somewhat unlike those other trades depend on...but accept re-assignment readily. The others, so-to-speak, are less inclined to help out.
