i wish i could post a pic on here to show you the piece but i never had much luck loading pics on here, not that good with computers, i ll take a pic tonight and try to get it posted. I went to a couple suppliers today looking for those stainless steel heat shrink disks but had no luck, although i am in northern canada. Where would a guy go to find those discs? Also i remember seeing in magazine one time a putty, it looked like play doe, that you would put around the area you were welding on to stop the heat from spreading, is that stuff any good? thanks
