The first thing that I found out about making a knife with a hidden tang is that you don't need to make the hole in the handle wide for the full length of the tang. If you have a blade where the tang tapers, you can make the hole taper as well.
If you make the hole too big, you run the risk of sanding down into the hole when you shape the handle. Yet, you can still come out with a really nice knife even if you fall into the hole.
