Step 2: From Home to Horn

Time to turn that snail's home into a musical instrument.
The objective here is to end up with a hole as wide as a U.S. Dime which will be the mouthpiece on the end of the conch. This means we must break off the tip of the conch. If you choose to use a saw, use ventilation and be prepared to learn just how tough a conch's shell is. If you use brute force, be careful to not take too much off. The key to remember here is that you can always take more off, but you can't put it back on. Over all, 1/8" to 1" of the tip will be removed.

Now, you'll notice a structure in the center of your dime-sized hole. Snap this out with a nail or center punch (1/8" to 3/4" of it may need to be removed). You'll see exactly what I mean when you do it.

Just smooth this mouthpiece with sandpaper or file (to prevent cut lips), and that's it!
