Hi! I would like to build the DIY PID Soldering Hot Plate at http://mightyohm.com/blog/2009/01/diy-p ... -hotplate/. I found the McMaster-Carr link and found several 1/2" diameter cartridges with different lengths. What is the length of the cartridge used in the project? If you know what the part number was, that would be great!
