How do I avoid electrostatic shocks hand sanding drywall?

[Beau]

Hi all.

 

I'm doing a bit of drywall work and I'm using the Mirka Handy sander with dust extraction to fair it. I keep getting hefty electric shocks from the extractor hose that are really unpleasant. I presume its electrostatic building up in the hose but do you have any bright ideas how to avoid this? 

 

This is the tool and its plugged into a Henry https://www.mirka.com/en-gb/p/Hand-Sanding-Kit-HANDY-80x230mm/

I get this too with the same set up so would be interested to hear of any fix

You can buy anti-static nozzles and pipes. But try an earthed metal adapter between the sander and the extractor.

May work.

Don't be tempted to earth your leg or aim, especially though your house wiring (was shown this on someone's Faceboom page).

So I may have a solution but it's not exactly neat. Went out to the shed to find some 1mm twin and earth to raid the earth wire and then spotted this. It's flexible electric fence wire. I was still getting light zaps until I threaded the tail into the pipe. Not had a shock had  for the last half hour. Suspect the wire could just be only inside the hose and come out by the Henry and still work. Tied it off to a rad.

OK so I've done a fair bit more sanding with no more shocks. Got it neater with the wire running inside the extraction hose. 

 

Markharrow if you want a length of the fencing wire I can send you some as we have lots of this laying about as we upgraded to heavier duty electric fencing on the farm.

How many grockles you hog tied with it, and how long do you need to chock them to stop them camping on your land.

We are only half a mile from the open moor so no temptation for anyone to camp in our fields. They can legally camp on Dartmoor, well most of it anyway.
