High strength hot melt for woodies. Be careful not to scorch the wood. Heat the point to where the glue will just be a touch runny and no more. Set the head and spin check for striaghtness.
For gluing inserts or adapters onto broadheads and points use JB Weld original. Set and spin test. Let cure over night.
Be sure and clean the inside of the points well with acetone,lacquer thiner,MEK or denatured alcohol. This removes the protective coating applied to the points.
Think clean clean clean when working with adhesives for good bonds.
