Step 11Running the beast!
Ok, attach it to the air line (nearly close the ball valve) and slowly open and close the valve until the hot side gets VERY hot. Honestly, this is trial and error here (make sure you're running the tank around 100-150 PSI) you'll get a feel for it though, However, you should probably never get the valve more then 1/4 the way open.
Notice that the more open you get it (to an extent) will make the hot side cooler, but the cold side MUCH colder. when you find that perfect place, and if the tube is right, if you're not careful you'll get some instant frostbite! yikes! Turn it the other way and optimize for heat (more closed) and you may get blistering air out the hot end! However you work it, the pipe should ALWAYS be hot when in use, if it doesn't get hot to the touch, you probably have the valve too open.
PS: I'd share a video, but, it's an unexciting whooshing sound with nothing moving (but the air) playing with it in person however, that's fun! Once you get it working and have a feel for it, think of the possibilities! freeze stuff in seconds!
