Jerry,
I've done a little grafting onto B-9, and I probably had the best success rates with bark grafting; I've done it with rootstocks as small as 1/4". For bark grafting your scion is still dormant, but you wait until the root has just begun to grow so that the bark will slip. There are good pictures of bark grafts in many fruit books, also in The Grafter's Handbook. It isn't quite as sturdy a graft for a few years so if it grows fast you may need to stake the new growth to keep it from blowing loose on a windy day.
