Ive read where several of the turn of the century (early 1900 or Pope era) shooters had low speed agitators on their pots to constantly agitate and or stir the lead while they were casting. I'm thinking of making one to run slow and just agitate the pot. It will need to be removable so when melting to start it is isn't there. I'm wondering if it will help keep the oxidation from forming and the consistancy of my bullets. I'm thinking an auger style blade in a short tube to pull lead up and off bottom to circulate and maintain mix. My pot I ladle cast from holds 100 lbs or so of lead. Its just a thought Ive had from reading some and wondering if it would be a benefit here.
