In the quest for stable melt temps I知 considering adapting a second 4-20 pot on top of my 4-20 pot so that the top pot ore melts the lead, and the lower pot receives little doses of lead that will allow the final pot to stay more stable in temps. I was thinking I could link the rods so that when I知 pouring into the mold the top pot is feeding the lower pot simultaneously. I知 already pre heating ingots but there is still a big dip in temps when I put in a new ingot or cold sprues.
