The ones of us that heat our broadheads are shooting wood arrows. We use hot melt glue to attached them to the arrows point taper, so we gotta get the head hot enough to keep the glue liquified till we get em turned just right & straight on the shaft. Then a quick dunk of the tuned head into cold water sets everything. Hope this helped. <img src=icon_smile_wink.gif border=0 align=middle>
