I am sure most of the posters here allready know this, but for the benefit of the newbies, two words, Mcmaster Carr. Any metal or material needed delivered to your door in a day. Even cut to the size you need. With all the manufacturing going overseas most of the local material supply houses are closed (at least around here). This company is amazing. Been using them for 20 years without a glitch. From leaded engravers brass, (clockmakers ) to cast iron rounds, (engine builders) they have it. No affiliation, just elation.
