Any suggestions? Back porch 20 inch or so?
I am looking.

Okay, my 2 cents.

I have a screened porch framed in wood.
We had a bunch of wind chimes out there.
One of them was made of light sheet metal and was hung too close
to the wood framing. Before I noticed, the chime had cut a gouge
in the wood about 1/4 inch deep.

In normal operation it didn't touch anything.
In high wind it did quite a bit of damage.

So, be careful with those things.

Since we installed modern windows I can no longer hear them from inside
with the windows closed.
