Off-topic I know, but I just nabbed a Rigid
9-gallon, 3.5 hp shop vac for
$19.97+tax. 7 foot hose, 10 foot cord. At your local Home Depot. They
have one that's the same or similar (Rigid, 9-gal, 3.5hp) in the tool
aisle for $58. This was in the front of the store. Someone from Atlanta
bought them too, I'm in WI. If anyone asks, I'll let you know the pros
and cons of the unit.
Sorry about the shill.
I got one very similar several years ago for Christmas (12
gal, 4.5 hp
Rigid). How does one make it static safe? or is that even possible?

I have read extensively about the dangers of static discharge in shop dust
handling systems. Seems all that moving particulate inside an ABS or PVC
pipe generates a tremendous static discharge potential. Most books
recommend snaking stranded copper wire down the inside of the 4-to-6" hose
and pipe used on such systems. You bring it out at the joints, smear the
holes with silicone RTV, and wire-nut it all together. I'd imagine you can
do something similar with a shop-vac, just use #14 or #16 wire instead of
the #10 they recommend for shop dust systems. One would have to get into
the motor assembly to find a ground, since that's as far as the line cord
goes. There's no metal anywhere on the beast, outside the motor and
impeller, so you'd have to have a ground wire in the bucket too.
