A quick video to show you my PID design. It is based off the PID created by Johnny's Reloading Bench and Loads of Bacon's modifications. I threw in a few of my own.
I decided to try casting 44 magnum / 44 special bullets by using two molds during the same casting session. The molds are the Lyman 429421 (the Elmer Keith SWC), and the Lee 429-200-RF.
Casting Keith Semi-Wadcutters with the Lyman 429421 Four Cavity Mold for .44 Special Skeeter Loads. I use my electric brewery equipment to control the temperature of the 220 Volt LEE Pro 4-20 Bottom Pour Pot.
Following are two videos that I have recorded and previously posted on YouTube concerning the PID Temperature Controller I use with my Lee 4-20 casting pot. I based my PID design on the excellent instructions provided by Johnny's Reloading Bench. Since he did such a great job instructing, these videos are geared more at demonstrating my assembly process. I have been using this setup now for the last year and have not had one complaint about it. It has worked flawlessly for me so far.
