Method of forming a tubular electrical insulator assembly
 A method of making a tubular electrical insulator assembly for an igniter plug comprising the steps of making a recess (11) in one end of a tubular insulator (10); cementing a portion of a tubular semi-conductor (20) into the recess (11) so that the remaining portion of said semi-conductor (20) extends slightly beyond the end of said insulator (10); and grinding an annular chamfer (21) into the ends of the insulator (10) and semi-conductor (20).
