[Shop-talk] water filter for blast cabinet

[Marc]

You know, this filter also makes a pretty efficient CAPACITOR...  
Apparently some of my water evaporated, and after running the thing a 
while, it took in enough glass bead to absorb what little water was 
left, leaving a very thick paste in the bottom. Soooo.... a LOT of 
static was generated, and was  STORED by the filter/capacitor.

So after working for a while I decide check on the filter. I remove the 
lid, reach in to remove the metal baffle plate, and WHAM! It knocks me 
on my arse and causes a mild case of Tourette Syndrome...

I took a jumper cable and tried to discharge it. Drew SEVERAL large 
discharges, even left it there for a bit. It still had plenty of juice. 
I finally had to use a couple foot long wooden dowel with a hook to 
dismantle it.

Yow!
