So how do ya get em out then ?, The old 2 nut method works ok on non stubborn ones most times but some need a stud remover which unfortunately can bugger the threads in the process,new stud time

need to change shops Lozza  ,the idea is to lock on the unthreaded section of the stud so you dont fork the threaded section,the stahlwille types the go,i have kokusan,basically the same style,the internal tapered rollers lock on the stud,whichever way you want it to turn,handy for setting studs too,

Heat the aluminium and heat the stud red hot.  The stud was fine it forked the thread in the cylinder, had to make stepped studs and tap the cylinder out.Don't worry Mick I have never taken anything  back there, the only threads that were still good were the 2 with no marks on them.
Long studs are frightening to remove, hard to tell if the stud is turning or twisting.
