Here are a couple of Manzanitas I collected this spring from a old unused road. They had been run over and broken by vehicles. A couple of nice jins were mostly broken off and hanging on by a few threads. They would have been lost during handling at some point so I went ahead and tried this technique. The Jin curved back and in the way of using a drill or screwdriver. I used marine epoxy because it dries white and (I hope) blends in a little better than regular epoxy. The nylon zip ties hold it tight without stretching while it's curing. If others have different, better ways of doing this, I'd love to hear about it.
