I carefully spread the crack as far as I can, then prop it open by shoving in a toothpick. Next I take slow-setting epoxy (1 hour set time) and, using a disposable glue syringe, inject epoxy as deep into the crack as I can, next I use compressed air to blow the epoxy further down into the crack. I repeat this process several times. Finally, I pull out the toothpick(s), wipe off the excess epoxy that squeezes from the crack, wrap the stock with rubber bands or rubber tubing and let the epoxy set up over night. If I can conceal it, after gluing, I will often drill a small hole, wipe in epoxy and screw a long fine-threaded stainless steel screw (one diameter larger then the hole) into the hole. I pre-measure the length of screw needed, then notch the screw with a file so that I can break it off below the level of the wood after its set in place).
