To Dan Statman I just purchased 14k gold tubing with a 2.0 mm wall
and an inside diameter of 15.5 mm, thats about a 5 finger size. I
got it from Stern and Leach. They can make it in most any dimesion
you could want. Nice people but be aware that they have a 100 dwt.
minimum for gold and a 100 oz. minimum for silver. I saw it off in
tapered widths and hammer it up to the size that I want. It’s very
nice for hand engraving!
