On the continuing saga of the electrode-through-chamber story...
I now secured some green TIG welding rods and see that this is
the material for my first aluminizing attempt.
For feed-throughs I plan to use glass as insulator with a hole drilled
through it for a conductive rod to pass through, using o-rings to
seal the vacuum. There is a decent assortment of sizes, but I have
no idea about best material. The shops here have nitrile rubber. Is
this OK material, or someone know this will not work (outgassing, etc)?
