In a monumental achievement, we actually installed our new sink last night.  Even more monumental, under prolonged stress-testing it does not appear to leak anywhere.  The key difference appeared to be, as the saying goes, “using the right tool for the job.”  The right tool in this case proved to be a pair of pliers.  As I plotted my next strategy yesterday, I remembered there were very few home or auto repairs that my Granddad couldn’t accomplish with a pair of medium sized slip-joint pliers.  He packed those things around like Dirty Harry packed a .44 Magnum.  In Garden City, legend has it he once rebuilt an entire engine in a ’32 Ford using nothing but his pliers and can of WD-40.  With a quick rummage through my toolbox I actually found that very pair of pliers.  (For whatever reason, every tool ever owned by a Kenagy has their initials engraved on it;  Makes it easy to identify I guess.)  They must still hold a few magical powers, even in my hands.  Everything went right together and worked in under an hour or so.  OK, I guess the sprayer doesn’t work.  But, like I said, the sink was given to us;  Beggars can’t be choosers.
