I've done a 15" and all you need is a 10" ring, center it up, and drill and tap through it into 4 of the spokes.
I don't know if I'd try it on a 12" because it would need a slight bit of machine work on the inside of the spokes to get the 10" ring to sit flat, and I'm not sure anyone makes 12" cones that shallow.
