Nice share!!
Blue Monster PTFE Thread Tape, thicker and denser, and comes in 1/2", 3/4", 1", & 2" versions, they now have smaller rolls available.
I’ll just post the link to the thread about controllers with both power regulation and temperature control, rather than going into it here. Even with the best PID controller the temp will bounce up and down if the wattage isn’t dialed in to adjust the boiling rate.
