Did a little research on removing inserts from carbons - called Gold Tip and asked them best method.

Although they truely didn't have a method they did indicate that they would avoid applying heat to the carbon as that is how they bond the layers, and if not very careful you could break down the bond.

They did indicate however that you can soak a carbon in and solvent (i.e. paint thinner, acetone, etc...) indefinitely and it will not damage the arrow.

I was told by the tech at Gold Tip that they remove old vanes by soaking the arrown in an adhisive remover like thinner for 5-10 minutes and they peel right off, and with a little whip down they have completely cleaned the shaft.

So they suggested trying soaking the insert in some kind of glue remover and loosing that way before heating the arrow.

Just an FYI
