Walked into a emergency job tonight . Broken 3/8-16 grade 8 bolt broken in an extruder pump flange . So far , made up a centering bushing jig , broken off 2 split point cobalts , finally got thru the bolt , then broke off one of my Irwin extractors . I have never broken one in the past 43 years ! 2 hours into it , I still have a broken bolt but have a nice pretty hole thru it .
I instructed the operator to take the temp up to 550 and I'll be back . If that don't work , the "heat wrench " is coming out . If that don't work , it's down to the EDM machine on Monday after dis-assembly of the whole friggan thing .
