Crunch Posted April 27 Share Posted April 27 Hey, all, I want to get into antique bottle hunting by finding and digging old privy outhouses, and one of the tools used to locate them is a "T" shaped probe made of spring steel that you poke down into the ground and listen/feel for glass and different soil consistency. You can find them for sale online but a 3-footer will run close to $70 with shipping, so I was considering attempting to make one myself out of some 1095 rod. It looks like one popular one is about .270" diameter. My questions revolve around how to temper such a piece about .272" diameter x 36" long to "spring" hardness. I guess to harden 1095 steel, you would heat it to critical/non-magnetic and then quench in water. I think I could pull off the heating and quenching in my coal forge...but... How would you folks go about tempering this hardened piece to "spring" hardness? Could I get away with quenching it very briefly (maybe in a piece of aluminum roof gutter so that I could quench the whole piece simultaneously) and then pull the whole piece out before it had fully cooled, and go by tempering color? Or will such a task really be too tricky/difficult for an amateur? Thanks in advance for any advice. C Quote Link to comment Share on other sites More sharing options...
