    Made an element and soldering tip for my Weller WPS18MP soldering iron. Used #31 insulated nichrome element wire, 8 1/2″ long, crimped each end attaching Teflon coated-PTFE wire. The nichrome wire was wrapped around a threaded brass screw, connected/soldered other ends of Teflon coated wire to the old pin connector (reused). Inserted the element into a SS housing I turned on my lathe, same style as old tip just longer. Please view my other video on how to build 3d printer bed elements here, same procedure, the soldering tips are just smaller, did not glue element in place either.
