Just finished working in my shop for today and decided to clean the dust inside the table saw with my HF dust collector. The hose is also from Harbor Freight, pretty good by the way. I think it has a wire inside the hose to keep it rigid. Or is it plastic ? It is not connected to anything though.
Anyway when I touched inside of table saw cabinet with the hose close to that wire it produced a huge bright sizzling spark. Very similar to what you see when shoring the electric outlet. I have no doubt it would ignite sawdust if it was closer. Still trying to calm down.
I actually have a grounding kit somewhere in the shelves, and I guess have a project for tomorrow.

Well, I guess i still think you’re worried about nothing…unless it knocked you on your butt. I find it hard to get sawdust burning with charcoal lighter fluid.

Carloz, think about this a bit, the tubing is plastic, plastic is an insulator, how much will the grounding kit do for you? Do you think the kit will ground a millimeter from the wire leaving the rest of the tubing just as it is now? FWIW

I used to use a Craftsman shop vac. I hated it because it shocked me all the time. Very annoying.

When my youngest son moved away about a year ago, he could not take some of his tools. He left behind a relatively new Ridgid shop vac. I love it. No more static shocking. I don’t know what Ridgid did in the construction of the vac or hose but they got it right. Nice tool for this dry climate.

I wonder if the dust collector hose could be necked down to accept a piece of the Ridgid vac hose?

One of the 57 reasons why I went with HVAC metal ducting instead of PVC ducting. I was never worried about starting a fire type of spark. But I do get enough of the “zapp” due to carpet in the home & work environments that I think I have brain damage after these 48 years!
