Gus!
Try a drop of oil on the tip of the drill. If this works frequently oil the drill tip. And avoid to drill with high speeds. Thus can melt the zamac, depending on its alloy and the melted zamac will clog the channels of the drill. A drill with clogged channels won't drill, it just turns "in his own juice".
Also frequently clean the channels.
Yes in those day zinc alloy was really zinc alloy, hard, durable and heavy.
Today it is an aluminium alloy with some zinc in it. The reason of the "lightweight" of todays locos.
