JW> Yeah, it used to be real fun making those poured lead joints on horizontal JW> CI pipes. We used something a bit like a piece of a V-belt to temporarily JW> block around the opening of the joint. It had a clamp holding it together JW> at the top leaving an opening into which you poured the lead. I never saw JW> one seal perfectly, we were always hopping around to avoid dribbles and JW> splashing molten lead.
JW> When the lead cooled we used offset "caulking irons" to whack the lead JW> down into the joint to insure a good seal.
JW> The guys who've never used anything except PVC pipes with glued joints JW> sure don't know what they missed.
