Attaching Magnetic Bit Adaptor to Screwdriver

In this video I attached a 6mm / 1/4" magnetic bit holder to the end of a damaged vintage screwdriver using two part epoxy.  I am a big fan of the handle shape of these red / blue Stanley screwdrivers and have been slowly collecting a set.  While amassing, I sometimes find damaged and unusable examples.  The tip of this one for example, had melted probably because it was contacted onto a live electrical circuit.  I tired to use a steel driver, but could not drill into a steel.  I therefore used a longer aluminium bit holder.
