Well Zodiac..There are about 5 billion ways to do this and everybody thinks that the way they do it is best.
I have two favorites. The first I didn't invent. It's called epoxy rivets..Drill a series of holes not too close together in the tang and make sure you get a good bedding of epoxy. It gets in the holes and makes a darn strong bond.
The second I think I invented. I drill a round hole in the handle material. I use a large enough bit for the tang to go in. (as opposed to using a smaller one and wallowing). I use an arc welder to raise spots along the tang high enough that they fill the width of the hole. I then build up a spot of weld on the top and bottom of the tang both front and rear. These spots of weld are ground into barbs just slightly larger than the hole. You will have to force the tang in but when it swells it won't move.
I use JB Weld to hold the tang in place in the front and let it dry. This keeps it fom oozing all over my guard later. After it dries overnight, I mix up a fresh batch and heat it with a heat gun. This makes it flow better. I use a wet swizzle stick to push it into the handle from the rear and every so often give it a blast from the air nozzle. When it's full let it sit with the knive tip in a vice. fter about 20 minutes check to make sure it's still flush, if not add some more.
24 hours later your ready to put on your cap.

One other thing. No what method you use it's important to rough up the tang and degrease. I sand blast it and solve both problems at once.
