What would it take to build a cryogenic cooler?

[Shingoshi]

Curious, do you plan on building your own vortex tubes or is there a factory shelf part within the sizing that you would need for your application?

And especially in the sizes needed for this application. I've made it my point lately to start using Google to get as many answers as I can, without having to ask here first. So try doing a simple check of Google for "vortex tubes", and you will see firsthand just how much of a selection there is for them.
