Eriks,
As you're sandblasting (or other media) the sand particals are colliding in
the air stream and with the work piece, knocking electrons off some and
creating an imbalance. Same principle that causes lightning or static
walking across a carpet.
Moisture content in the air is a factor, the effect is most likely to happen
now that winter is starting to settle in (cool dry air, typically!).
Cheers,
Jim
(whose kitten is learning about static electicity today! :-(
