at my age, generating sparks is the LEAST of my problems. AS to my crotch getting hot, no big concern there, either ! Getting Zapped is not a concern , just understand basic electricity - problem easily solved.Sitting in a chair or stool while grinding comes up on forums every now and then . From what I've read its more common than we think or care to admit. Biggest complaint i saw were guys sitting to close to the sparks. Seems they didn't like their crotches getting hot. Second was sitting on metal chairs/stools and getting zapped .
Hope you find a solution and things get better.
i don't think things can get much better. I mean, I live in the middle of a national forest. I don't have any extra bull in my life. Been married to the same girl for 36 years. raise our own food. can hunt and fish when I want. Can practice shoot off any of my decks. My life is so much better than most of the people on this planet. plus, I don't have a cell phone !
