[Amilo]

I have a 6 year old Pear grown from seed as a Espalier, but it has never produced a flower, OK I knew is was a long shot that any thing useful would come from it, so I had set my mind to root it up, then I thought it must have a good root system by now I wonder if I could graft something onto it and save the day!

Has anyone done this that could give me some pointers?
