Here is the way I did it.
First, wax the stock, then clamp the crack closed, (tight) then drill a 1/8" hole down the center of the crack. Make sure there is no "sawdust" left in the crack! Take the clamp off and insert a small knife blade in the crack. Use a good two part epoxy that mixes as you depress the plunger. Put the small nozzle against the hole, and inject the epoxy into the hole until it comes out the other end of the crack. Clamp the crack closed again, and let set.
Refinish stock.
