Super Freak
There is a simple solution that I got from a YouTube vid. Gently take the open mouth head, tilt the head all the way up , gently push the jaw into the head , at the same time, with your thumb hold the neck post ( gently ) and pull back the head until it pops off
you will see it pop off the peg , remember don’t use a lot of muscle. Do the same with the smiling head
It really beats heating up the head all the time and using tweezers or pliers because you can damage the neck peg
I’ve been using this method , no problems
I shall try thank you, much appreciated.
