How to drill star safe

[1carwash1]

can someone please pm the directions to properly drill a star safe head. additionally, the safe head has not been opened for at least 25 years and is rusted in place (cannot rotate safe head). Been applying pb blaster, but the head is still stuck. any Ideas or suggestions to loosen up the head?

I have had success by boring a hole in the column and whacking the studs with a big Hammer and punch. That only works though if you know where a stud is. If it’s been 25 years you might be better off renting a chop saw and chipping hammer and start with new.
