re: Has anyone else here ever created Water Hammer?

This is what I do for a living. On a domestic scale, you can probably just add some standpipe to the plumbing line if you have the vertical space, you can slow the closing of the valve, or otherwise reduce the acceleration of the fluid. Anyone who hates the sound their ice maker makes when it stops filling is experiencing water hammer. Standpipe is similar to an alternative benefit that water towers serve.

On an an industrial scale, I have seen 8" steel pipe severed in half, pumps, relief valves, and instrumentation destroyed.

I can calculate the volume you'd need to eliminate or make it tolerable for you if you want.
