Where to buy 6mm brass or stainless steel tubing?
Does anyone know where to buy good lengths of 6mm ID stainless steel or brass tubing? When I say good length I mean like around 4 feet continuous. And the tolerance must be very good, in the degree of 0.01mm I’ve been searching for a while, but getting metric tubing in the US in lengths of anything more than 10 inches or 300cm is hard.
