| 57834 | 2002-06-28 12:38:00 | I perhaps should clarify its the dust in the air speeding down the hose and touching the plastic that builds up the charge, not pure air (in case you wanted to know) Compressed air from a compressor is bad due to minute oil particles speeding out. Canned air *should* be OK? As to the FDD problem, when a new drive is about $45, a second hand one would be ?? how much trouble is it worth? |

Don't risk it! That would be the bit hubby was worried about. I didn't get that close! Very interesting stuff this, thanks for the info. BTW godfather, does SWMBO vacuum your car as well as your house? :D |

| 57836 | 2002-06-29 00:33:00 | I can vouch for the fact that vacuum cleaners can create a terrific amount of static. Had a job once painting some beams and had to vacuum them before painting and there was so much static that I had a red mark like sunburn around my back where it had been touching the metal cage through clothing. | mikebartnz (21) | ||
| 57837 | 2002-06-29 00:55:00 | Yes Susan SWMBO washes and vacuums the car(s)....isn't that her Raison D'Etre?? On receipt of a works order or cheque (payable to cash) the report will be forthcoming...Standard rate is $100 per page. |

| 57838 | 2002-06-29 03:15:00 | If you've got low humidity, you might get a bit of charge . I don't think it would happen much in Christchurch at the moment . About 70-80% this morning . If you're worried, a soft paintbrush to disturb the dust and gravity will do the rest . You have to remove the drive to get the cover off it anyway . I remember being warned about static from gas flow when I was doing some work with hydrogen balloons . H2 can catch fire from the charge when you "crack" the 2000 psi cylinder . So I used conductive rubber hose and copper fittings to fill the balloon . That was all right . Since it was a tethered one, I then had to deal with the balloon after it was pulled down . It had been to 500 ft (and the voltage gradient is about 100 V/m -- say, 30 V/ft) . I tossed the scissors at it . Gentle "puff" sound, and the shreds of the balloon fell the last 10 feet . I don't think that your vacuum cleaners are that good . |
