I built a cattle gaurd out of stem a while back and had to wrap the ground lead around the stem 4-5 times like said above and found putting a little heat in it first worked really good to keep the stem from getting brittle. that stuff is a pain in the rear. after I got the cattle gaurd finished I gave the rest of the stem away so i would never try to build anything with it again. good luck
