Custom made PVC K5LA train horns

First and foremost, I would like to thank Harold Meade for the help he has provided during this project. I would have not been able to do this without you. And also thanks to Dozerboymiller for the idea of PVC for air horns.

This is a custom set of air horns tuned to the notes of the K5LA train air horns ( D#, F#, A, C, D# octave). The idea was based of the horns made by Dozerboymiller with the help of a few other people, one of which was Harold Meade.
The horns have a 3" diaphragm (air chamber and diaphragm) with custom made fiberglass bells. They are plumbed with a 3/8" air line to get the maximum performance out of each horn. They operate on an average of 90-115psi putting out about 110-125 decibels.
