Ok here are some images of what I call the Cryo-Feed-Thru. It facilitates getting the final stage Feed and Return out from my insulated HXC box, into some real world connections (Swagelok VCR's). The inside of the stainless tube will be polyurethane foam insulated (same as HXC box), and a special saddle clamp (not shown) will be used to secure it to my Tslot frame.
I can only take credit for the silver solder work on the inside of the cap. A friend of mine at the place I contract to, did the excellent tig welding of the cap to the tube.
I should have more pics of the Feed-Thru being used in the complete assembly within the next week. I'll be sure to post them.
