in my previous very verbose post above ... OK, on the previous "page" since there are ten posts per "page".
Seems like fingers are stronger than I was willing to believe. But when I think about it, people put some pretty good stress on just a few fingers. Think of an archer: two fingers or three, up to a hundred pounds of force to draw the bow, no sweat. Or think of a hammer thrower; I don't know how heavy the hammer is, so I cannot calculate the force, but it's probably pretty high. OK, I am convinced. My figures are right.
TechStuf,
No, unfortunately my neighbor's upper-story windows are quite within range of a rogue shot. I haven't hit them yet. I haven't even dropped anything in his yard, yet. Still, I don't sling anything but tennis balls within range of his yard.
I've been concerned about equipment failure, with those snap swivels ... I thought I was well past the possibility of operator-error rogues ... until yesterday when a snowball slipped out of the pouch, went nearly straight up, and dropped twenty feet away at the feet of my wife and a friend we had visiting! Missed them both by less than a foot, and I was still looking up and trying to figure out where the snowball had gone. My wife's look was sufficient to sizzle me where I stood!
