Like so many foundries, it wasdominated over by a superintendent whomight have been a capable machinist,but he knew nothing about a foreman was what would be calleda filler in a big foundry. He could workwith a gang or he could do good enoughmolding on trinkets, but he was notup on details. However, this job washanced to the men and they were sup-posed to make it, and as I have shown,it met with poor success until it got to. Two ways of gating cast smoke stacks Why pipes are frequently defective on upperside not against the bare core. If this re-quires a pop gate which will be biggerthan can be kept full, the casting istoo bulky to be poured with a pop have been successful in a number ofcases in pouring fairly large bplacing the gate right on top of thecore print, and cutting it into theend of the core. In fact, I always pourbuilding columns that way, as it makesbetter castings and is more easily donethan any other way. I remember making some cast ironsmoke stacks for road engines in ajobbing foundry. The shop where theengines were ibuilt was over-crowdedwith work and had to let some of itout. In the shop where they were manufactured, the rule was to put about adozen pop gates about the size of alead pencil along the top of the pat-terns. A big basin was built on top,big enough to hold all the metal re-quired, and when pouring, the metalwas just dumped into the
