Sapper alessi kettle

I bought new pitch pipes for my kettle and they came with directions. The directions from Alessi say to push the old ones out from underneath (part of the whistle that rests inside the kettle when it is closed) with a flat head screw driver. When installing the new ones, they say to only use your finger to push them in from the top, using only the eraser end of a pencil if you need to push with something. Mine were very loose, however. Also, the side with M1 or S1 etched into the brass part of the whistle should go lettered-end down into the brass tubes.

You need to find something strong and the right diameter to fit through the hole in the back, to push out the old pitch pipes. I used a twist drill - it doesn't matter if it gets trashed doing it - it does not work anyway!

Push the new ones in gently, they should go in easily, if they are a bit tight make sure the hole is clean. Clean it out with some wet and dry sandpaper.
