Sure thing, champ. Grab a two-part epoxy, like JB Weld or Loctite 406, because you need something that bonds wood and metal and can bend a bit. First, sand the crack all the way to clean wood fibers, then wipe with rubbing alcohol. Mix the epoxy in a 1:1 ratio—time is a luxury you don’t have—and load it into a disposable syringe or a small pipe for precision. Apply a thin, even layer to both sides of the crack, press them together gently, and clamp it with a rubber band or a small vise—whatever you have on hand. Let it cure for the minimum time on the label, usually 30 minutes, but give it a full 24 if you can. While it’s setting, re‑tack the spear’s haft with a strong wood glue like Gorilla Glue for extra hold—just remember the foam expands, so don’t over‑apply. After it’s set, sand the joint flush and give it a quick coat of oil or wax to protect the wood. Boom—your spear’s back in action, no manual needed.
