My buddies shotmaker is letting 2 pieces of shot stick together,he can break them apart with his fingers,he is using cutting oil,could this oil be wearing out? or getting to hot? This just started happening,anybody have any advice?? Thanks John
The coolant is getting too hot and the shot are not solidifying before they contact each other in the bottom of the tank. The answer is more coolant or stop production until it cools enough to carry on. I have had lead stalagtites form from hundreds of lead pancakes that build up and eventually come thru the surface of the coolant because it was too hot.
Andy- I fully understand what you described. Adding more lead to the pan can also cool down the lead and reduce the drip rate. With a little practice, the sound the shot makes as it falls into the coolant can indicate if things are good or bad.
What coolant is anyone using? Antifreeze I've heard is the best but is there a kind thats not toxic? I've used oil and diesel and better results with the diesel, but the smell and cleaning of it are really hard. And in the winter its really hard to get the lead to flow good unless the room is really warm.. Thanks Linn
