So dry in the winter that I can pull a spark from a painted surface on my lathe or planer  Figure it's the rubber (pun?) belts that charge 'em.  And both are grounded, of course.  

Tough to ground an insulator.  Conductors, yes.

My belt sander shocks the crap out of me when I have the shop vac hooked to it.

I've accidently sent sparks into the shop vac while sanding wood. If that didn't ignite the sanding dust I don't think anything will.

In my first shop I went through the process of grounding. Second, and larger shop, I did not. I don't see any difference whatever. This comes up every once in a while and the evidence for real concern in a hobby shop environment is nil; now, to be clear, in an industrial production environment there is some data IIRC, but we are talking about huge dust collection systems.

How important is this?

All I know is when I touch my flex tubing I will get a shock so I am going to put it on my new system.
It is always the right time, to do the right thing.

If you ground just the spiral wire in your flex tubing, that may be sufficient.

I think this is well over hyped.

How would I get both wires connected together?

Even if you discount the fire danger, getting shocked multiple times a day becomes a comfort in the work environment issue.  If the shocking continues I will eventually ground what needs to be grounded so I don't fear using my tools.

All you would need to do is to nick the outside plastic layer to allow you to connect a wire to the metal spiral of the flex tubing, and connect that wire to something grounded, like the chassis of the DC itself.  Or you could get access to the spiral from either end.  This is just to keep from getting shocked when you touch it.

Thanks for all the replies.

My niece does some very nice arts & crafts jewelry from wire.  I think I will donate the copper wire to her.
