  I made a Hilsch tube in my shop this weekend. It's quite impressive! With just a little experimentation, at 80 PSI. the temperature is 17 Degrees on one end and about 70 degrees on the hot side. The pipes are 1/2" PVC. The center hole where the vortex is formed is 11/32" with a 1/4" hole in the washer on the cold side. There are 4 equally spaced Drill #53 (.059) holes Tangent to the center hole that forms the vortex. The valve on the hot side is from a old air tool. It's quite loud and you can hear the air "spinning up" like a turbo! It uses lots of air. Pictures sent to Phillip Torrone.

  Hello earla or anyone else who was more clear than myself on the details of the 'POKER' project. The center 'washer' has a pretty diagram/description and earla provided real dimensions. I am unclear on the other two washers. In the article it appears that there are just some holes drilled through the center, but earla described drilling out one of the washers differently. From the article, I don't see the purpose of the two outside washers. Can someone please fill me in? I two would like to see a photo or even a sketch from earla.
  
  Thanks all,
  Brian

  Sounds like it worked really well for you, I for one would love to see some pictures too. (
  Thinking about trying my hand at making one as well.)

  Hey earla, Would you like to come to Maker Faire and show off your vortex tube? We'd be delighted to have you and your tube.

  Fantastic! Impressive results!
  
  I assume this is just using shop air?
  
  I don't quite follow your description of the vortex itself... I guess I better get the photos from Phil.
