Continuing where this thread drifted into some talk about modifying the PM2...
I'm at a point where I no longer want to mess with the asinine thermocouple that is attached to the heating element. The modification here will be to detach the current thermocouple from the PM2's PID and install a new thermocouple that will be mounted externally and take temperature readings directly from the melted alloy.
Part of me really wants to just gut the whole internals and make an external assembly with a better quality PID controller and one that I can actually get full instructions for. However, I'm stubborn and frustrated about overpaying this much for a bottom pour pot with an inferior and poorly thought out PID design. Therefore, shelling out any additional cash for anything more than the external thermocouple is a no go.
So today, I stripped the external parts of the pot so I could get to the electronics inside. I'm 99% sure I have located the thermocouple lead, but I thought I would ask the group here to verify if I am correct. Silver braided wire that is coming from the crucible side of the pot and then leading to the PID with red and black wires. Black has a blue crimped forked connector. Red has a red crimped forked connector. That sound right? Now just swapperoo?
Recommended Bottom Pour Lead Furnace
Art Green's RCBS pots were there long before 1998 They were there in the early 80's when I would drive to Beverly hills for WW alloy. Old Art was a great guy but nearly drudgery to go there because he would talk your ear off for hours on end if you let him. There was absolutely no quick in &...
