Claim 1

IN THE MANUFACTURE OF A COMPOSITE ELECTRODE COMPRISING A REFRACTORY WIRE COIL OF LINEAR CONFIGURATION AND A CORE MEMBER HAVING AN END PORTION THAT IS LARGER IN CROSS-SECTION THAN THE INSIDE DIAMETER OF SAID COIL BY AN AMOUNT SUFFICIENT TO ENABLE THE COIL TO BE LOCKED IN ASSEMBLED RELATIONSHIP ON SAID CORE MEMBER SOLELY BY MEANS OF A FORCE FIT, THE METHOD OF ASSEMBLING SAID WIRE COIL AND CORE MEMBER WITHOUT PERMANENTLY DISTORTING THE COIL AND CHANGING THE SPACING BETWEEN THE TURNS THEREOF COMPRISING; HOLDING ONE END OF THE COIL AT A LOCATION SUCH THAT THE COIL IS HELD STATIONARY AND ITS INTERIOR IS ACCESSIBLE ALONG A PATH COINCIDENT WITH THE LONGITUDINAL AXIS OF THE COIL, ROTATING THE CORE MEMBER ABOUT ITS LONGITUDINAL AXIS, INSERTING THE END PORTION OF SAID ROTATING CORE MEMBER INTO THE AFORESAID END OF SAID ALONG SAID PATH TO TEMPORARILY ENLARGE THE PORTION OF SAID COIL ENGAGED BY SAID CORE MEMBER AND THEREBY ENABLE THE LATTER TO FREELY ENTER THE COIL, CONTINUING THE CONCURRENT ROTATION AND INSERTION OF SAID CORE MEMBER UNTIL SAID COIL IS LOCATED IN ITS ASSEMBLED POSITION ON SAID CORE MEMBER, AND THEN DISCONTINUING THE ROTATION AND AXIAL MOVEMENT OF SAID CORE MEMBER TO PERMIT THE TEMPORARILY ENLARGED PORTION OF SAID COIL TO RETURN TO ITS ORIGINAL SIZE AND THUS COMPRESSIVELY GRIP THE CORE MEMBER.
