What type of hose?

[Unckdecamp]

Thank you to everyone for your suggestions....

I am going to try and figure it out!

You will want a bare copper wire, usually stranded (not solid) "inside the hose" to handle static.
(From the dust foot to the vacuum)

It will have to exit at the vac unit and be tied into a good ground in some manner.

We just re-did ours,
skinning off quite a few more feet of insulation, in continuation of what was already bared.

We now have about 15 ft. of bare copper wound around the outside of our 9-10?ft. length of 4 in. vac hose
starting from the upper end of the dust-foot's 'upright'
and ending where the tubing disappears into the PVC vacuum tubing, up in the ceiling.

I made darned sure the wire stays in close contact with the tubing
by winding it tightly around and in some of the corrugations
and then taping those tight windings in place, every 16 ins. or so
to make sure they stay there!

Result: we get no static in our air-conditioned Shopbot room.


I also took the length of vac.hose off the machine
and washed it thoroughly inside and out
-the first time that's happened in ten years!

You shoulda seen the red-brown water that came off it!
Can't help but think that too helped with static reduction..
