A little heat on the metal parts will gooifiy the surrounding epoxy. Then extract and clean

 

Don't overdo the heat. Use just enough to soften. I don't think that the temps we are talking about will change the characteristics of the metal. Someone with more knowledge, chime in.

Kill two birds with one stone. If it's a bushing, try drilling the bushing out with progressively larger and larger bits. When the walls of the bushing get thin enough, the heat from the drilling will gooify the flox (as Rich said) and if you're lucky the bushing will spin out of the layup and onto the drill bit. Just ensure the progressive drilling stays on center and doesn't get too too hot.

I think Wayne meant the heat emanating from the drill bit boring out the bushing will, with luck, be sufficient for dislodgement.
