Wear dish washing gloves, it stops up to 2kV, but don't use them for lethal currents.
Chemical gloves are better, as the electrodes are copper just tap them with an insulated screwdriver.

PROGRESS!!!!
It
was a nice and shiny virgin piston... then I had to vise it to thread the back end...
Then I oiled it.
To prevent rust, of course

get one of those rubber jar openers and put it around anything you are putting in the vice, that way it wont damage it.

I tried that
Incrementally tightened the vise until it could hold the part, but my vise put holes in the rubber when I got it there.

get some soft jaws

...or ben two copper plates to fit in the vice. The soft metal won't damage stainless steel.

Just an idea I'm throwing together in the hopes that it works. Some progress below:

Progress has been made, but camera battery is dead. Will post pictures when battery is charged and epoxy is cured
EDIT: Gaaaaa went overboard with the curing temperature. Curing epoxy runs like crazy at 400F

Patience is a virtue, stcik to 50 degrees celcius max and wait
remember that heating is also causing your components to expand, meaning they will contract when you return to ambient temperature, in some cases this is enough to make a joint leak.

Yeah... at least this component will be entirely within the chamber, so no worries about leaks.
Sanding glass is a female dog. Taking a break now, but I'll probably have something this evening.

I have 133t ski11z. I made type 304 SS rust.
Epoxy adhesion to polyolefin heat-shrink tubing is being tested.

Epoxy adhesion to polyolefin heat-shrink tubing is indeed poor, but I'm not sure if I can cause a shear failure, because I was only able to evaluate the tensile adhesive strength in preliminary testing.
More practical test setup is curing right now.
