First pipe

I made the first pipe with calculations from WebPipeCalc. Below you can see a few pictures of its original state. I tried to make a C5, but even with the tuning slot fully open it sounded like a B4, so I had to shorten it a little.

And this is what it sounds like:

Pipe 1

Pipe 2

Pipe 3

Pipe 4

Pipe db(A)

(measured directly at the mouth of the pipe)
