Welcome Emmanual.
My schoolboy French is long forgotten, but Mr Google suggests:
Hello everyone, I bought a mimnie, and I would like to give it a whistle.
The only possibility is to install it on the steam chest, do you have another idea, very little space between 2 screws. And what diameter to drill, I am in metric, thank you all, Manu.
Guess the engine is a Minnie.
Anyone got an answer?
