I am liquidating my uncle's estate. He was a truck driver for most of his life, so maintenance was a daily thing. He has so many tools and odds and ends. Piles and piles of stuff. I found this. It has a manual crank and looks like it used to be bolted to something else. It has an armature of sorts. You guys will know what it is, I have faith.

I’ll be darn! In the mid ‘80’s I used to have to go to Taiwan for work. On the way from the hotel to the company I hear a “booom” and turn and see all the water flying up from a pond. I asked the driver what was going on. “Fishing”. Seems they’d toss dynamite into the pond, concussion killed the fish and up they came.
Like the old joke.... Cop comes out because of a call about loud explosions. Finds an old man standing next to a lake, lighting sticks of tnt and throwing um in the lake. Cop says "whoaaaaa buddy, what the hell do ya think you're doin there?". Old man says "fishing". Cop says "Yeah, that's illegal, you can't do that". Old man stuffs a lit stick into his hand and says "you gonna talk, or you gonna fish...."
Ha ha, yeah we used to do that as kids before going fishing - wet the ground, stick a wire into it, and hook the other end to our electric fence. In a few minutes, unhook the wire and pick up the worms that had crawled to the surface.
We had one in the science lab in high school. We would try to see who can endure the shock the longest by holding two wires while the other guy cranked it. We also used to torture this one poor sap. A few of us would sneak up behind him while cranking it while one of us would take the wires and either zap him in back of his neck or for extra points zap his ears. Naturally we would do that to each other too.
