nclonghunter, all the epoxy i have ever used can be heated up to a certain temp and the adhesion properties
of the epoxy will let loose,much like other glues

i use epoxy on knife scales and some stone to wood knife glue ups
there have been times i didnt like the scales i put on and just used my heat gun untill the epoxy let loose
as far as hafting stome points
all i ever use is pine pitch and sinew
but i dont hunt with the primitive arrows i make(illegal to use stone where i live)
they are just wall hangers so i keep them as primitive as possible
i for one dont beleive i could use epoxy on a primitive arrow or knife and still call it primitive
