First successful air horn test!

I’m very pleased to have successfully sound tested my prototype air horn / train horn for the first time!

Using a (poor quality) test battery, we were able to get the air tank up to 40PSI, the hardware is rated for 120PSI, however based on this test, I think we need a more remote test location before going up to higher pressures.

Now we have a working prototype horn, and a working brain, I can begin planning the construction of the entire instrument. Watch this space…

Here are the files for anyone looking to print these horns. Many thanks again to Sarah Tamsin for doing the prints.
