I was going to tap my holes, like mentioned above.

BUT, I was going to use a tap that was only very slightly bigger than the hole itself so that shallow "threads" were cut instead of a full thread cut that would normally occur.

Before I did that, I was going to try a longer "swirl" cut, but didn't know how to do it. I do have some long screws used in plastics - they only have about 2 threads per inch. I don't know if they would cut into the copper though, perhaps if I modified them...

I originally thought about putting a spring inside, but thought the cutting of very shallow threads would turbulate just as well, AND add slightly to the surface area.
