The Pedal Pipes

Today, I cut to length the pipes for both divisions. The middle pipe is 3/4" diameter and the thickest. This would represent about a 9' diameter on a 16' pipe which I think would be right. From there, I just tried to (proportionally) fill the chamber.

Diameters from Center back (symmetric): 3/4", 5/8", 5/8", 1/2", 7/16"

After cutting them all to 16 inches, I needed to mark where the mouth would be, which is where I will start the taper of the pipe.

Notice the pencil markings where the mouths will be located

As far as HOW I'm going to turn these things down. I will need a lathe, obviously. I'm hoping that I'll be able to use one where I work. I will find that out tomorrow.
