There is a lot of good information out there about that period of hockey; rules and equipment changes, not to mention the spread of the league into the US, caused upheavals in the game.
I finished the story before I found the answer, but I did find the answer. One man scraped the ice with a shovel, one man rolled something like a giant bucket on wheels that sprinkled water and the last man evened the ice surface with a broom. The process could take up to ninety minutes. I haven’t used that piece of information in my fiction. I probably won’t but I know that my characters would know.
I am very thankful for the Zamboni. And I bet my characters are to.
