From time to time members ask questions about how to remove stuck studs from castings.
While refurbing some brake callipers I encountered a stuck bleed screw. It was rounded and a heat gun and vise grips would not budge it. On the plus side it was not snapped off and easy to get at.
My favourite method is to use a welder to heat the stud.
Fit a nut to the remains of the stud. In this case I had to drill the thread out of the nut. Weld the nut to the stud (bleed screw). Let it cool a bit and unscrew it. On the third attempt it came out. No damage to calliper.
Whole process took 25 mins and that includes rummaging around for then drilling the nuts and taking photos. Actually creating this post took longer than doing the deed.
