As stated above, I now have two broadheads with the broken "cone" of the adapter now stuck inside.  The adapters were 75 grain steel epoxied inside of 160 stos heads.  Heads are in good shape and would like to keep them but cannot get the cone out.  Help and advice is greatly appreciated.

try a heat gun....or you might try soaking in acetone...

I Myself Would Grab The Head With A Big Pliers, hold It So I Could Look Down The Hole Of The Ferrule, Then Put The Flame From A Torch Right There.  When The Epoxy Or Glue Melts. The Heat Will Pop The Adapter Out.  Having A Second Person Holding The Other Side With Pliers (By The Blades) Acts Like A Heat Sink To Keep The Blades From Getting Too Hot.  Cool It Off Pretty Quick Afterwords.

epoxy breaks down with heat just don't get the head so hot you loose the temper

Heat the adapter and it shouldn't affect the broadhead.
