Last night at Lowes I saw that they had PVC unions so one in 3/4" and decided to build the simple burst disc. I will fire it tomorrow when the glue is all dried.
This gun is the definition of simple and cheap. For a beginner this is as simple to construct and fire as a basic combustion. Great gun to start out with.
