Eons ago I took a workshop and used some 5 or 6mm square tubing. Not
thick walled. Am looking for this now. Can’t locate anything. Not
Stuller, Rio, United Precious Metals, etc. Can anybody point me in
the right direction? I only need a foot so won’t meet a high minimum
some folks require.
Call Myron Toback in New York: 1-800-223-7550 They carry square
tubing in a range fo sizes from 2mm to 19mm, wall thickness is 0.020"
They have a $25 minimum for shipping.
