THIS IS NOT A VIDEO ABOUT OPERATING AN OXYACETYLENE TORCH! IN PART OF THE VIDEO IT MAY SEEM LIKE ALL IM DOING IS COMPRESSING THE CORE BUT WHAT IS ACUTALLY BEING DONE IS ME TRYING TO GET ANY MOVEMENT FROM TOP PRESSURE TO BOTTOM MOVEMENT. SURE THE BOTTOM IS BLOCK FROM COMMING COMPLETLY OUT BUT THERE ARE AREAS THAT YOU COULD BE ABLE TO SEE MOVEMENT EVEN JUST ALITTLE BIT.. WHAT IS STOPPING THE CORE FROM COMMING OUT IS THE WELD JOINT INSIDE OF THE TANK.. ITS LIKE A SPEED BUMP OR CURB TO THE CORE.if you plan on doing this, do further research. I'm only sharing my own experience and knowlege. but other wise this video is carefully removing core from acetylene tank for the first time to see what it would actually take. don't use grinders. portaband is safer.
