The bad part is that you will get nipped a few times while teaching him not to nip, just be prepared to get nipped but try to touch his beak, this works best when he's out of his cage, or even in a different room that he's not accustomed to.
When you reach for his beak, he can see your finger so that helps him since he can tell if you're going to try anything so he should allow it if you aproach him calmly. If you reach for his beak but you're nervous, he'll detect this and be ready to defend himself so you'll need to be as confident as possible, then just touch it and reward him. even if he's trying to nip at you, reward him if you can touch his beak, even if it's just a split second. Work with this for a while and you should see him begin to get comfortable with your finger on his beak. This can take anywhere from about 10 minutes to a few days... just reward him anytime you can touch his beak, but when he starts to bve more comfortable with it, try to pet his beak and reward every time you can pet his beak, work with this until he's ok with you petting his beak, and reward every time. Once he's ok with this, you can pet his beak but work your way to his cheek feathers. Birds love being pet on the cheek and the forehead so this should become easy rather quickly.
Just work your way to where you can pet him, then you can begin teaching him other things like stepping up to your finger instead of a stick etc...
Also see my replies in this thread for "gentle beak" training your bird... viewtopic.php?f=11&t=11062
I've trained all of our birds with this and it does work, it works fastest on a yourn hand raised bird, but it can be done on any bird, it just takes longer on parent raised birds and birds that have been caged most their life etc. Once your bird catches on to the gentle beak training the biting and nipping will stop and then you can teach him just about anything or just put him on your shoulder while you're reading, studying, or watching tv etc... Birds love to sit on our shoulders and there's a nice warm neck for them to cuddle into so this is a way to form a bond with them and help them lose all fear of you rather quickly.
