Assembly

So I finally got my Ruben's tube working. As there are many instructions online, I will not go into many details. Basic steps I took:

1. Drill 96 holes each 2mm in diameter and 20mm distance apart alongside the top of the pipe.
2. Weld one side of the steel pipe shut.
3. Weld two small steel pipes, 10mm in diameter and approximately 50mm in length, into  the steel pipe for connecting the gas tubes.
4. Sealed the other end of the steel tube with a surgical glove and duct tape forming a rubber membrane.
5. Connected grill gas supply to the steel pipe by splitting one gas tube coming from the pressure adapter into two and connecting each of them to the small welded-in pipes.
6. Placed a Bluetooth speaker in front of the membrane.
