"I just use the same heat glue you would use for aluminum"
Duh, to me.
Probably my first choice since I've been using it for aluminum arrows for some 20 years - Bohning Ferr-L-Tite Glue. And its recommended for carbon arrows too.
"Ferr-L-Tite Glue is a hot melt cement which can be used for both aluminum and carbon arrows."
And I have some already on hand. Been melting it on the kitchen gas stove that long too. Got that melting system down.
If it works, I don't really like to change. And getting older I really dislike those old new tasks around the house, that you haven't done in over five years.
Thanks for all your options. Just because it's different doesn't make it bad. And I may get around to a new glue. Even my old fletching glue has changed. With today's change, you need backups. Even the aluminum arrow co. sells carbon arrows.
