While I am not an advocate of CA, this may be one of those times when it is the best solution, if you have a nice tight fit, place the stab into position and lock it in with thin CA. If there are any gaps, carefully fill with soda (that powdered white stuff used in the kitchen) making sure none is built up where you do not want it, and then hit it again with thin CA. Instant rock solid bond that will destroy the wood before the joint breaks. Any imperfections outside the area will be very difficult to sand out, thats why you make sure there is no build up of soda outside the area you want it to be before you add the thin CA.
