Maybe to get the ball rolling, do your own will with a software package, show it to your dad and tell him you did it yourself and it only took an afternoon, whatever.
Then help him do a simple one if he sees how simple it can be. Once he has something at least, then if he does need to consult an attorney hopefully the ball will be rolling enough for him to want to do that.
Does he have any friends or acquantances with wills? Ask around. Ask them, "I'm having a hard time convincing my dad he needs a will. Can I ask a personal question? I'm wondering if you have a will if my dad can talk to you about the process." If they say yes then ask your dad to talk to them.
What is his learning style? If he learns by reading give him short articles. If he learns by hearing give him a short video.
Good luck, I've been through this and still going through it.
