Lathe I borrowed yesterday was filthy,....so I soaked the lift pipes I'd pushed through it's spindle bore overnight, and scrubbed the beJesus outta' em' this AM early.
Wind WAS up, so TIG was not an option,....Blorped hot MIG at squared up and prepped couplings instead.
Pickled em' in PP again,...Mig / anti spat spray I'm using
is water soluable
