I would like to ask if anyone has an internally mounted thermocouple similar to the one in the pic below. I'd like to mount this in the center of the bottom of the pot using flat washers on both sides and locking them down with nuts to clamp and seal the drilled hole. Hoping the 4-20 pot arrives this week so I'd like to get some experience from others. I also have a Lee Magnum Melter and would like to do the same to it.
