It's a wide handled D bow- 1 1/2" wide, and 7/8" deep. I was thinking about using the same type as you were using (having read the article you are refering to), only with a tougher metal sleeve. The entire bow bends, and there isn't a whole lot in the handle, though there is some. I think I will wind up using a hinge, as this would simply have the two peices of wood pushing tightly into each other. I would have to use a shorter alignment pin of course, but none the less. I guess I'll just have to see how it all goes.
Oh, and sorry about my initial post, I was typing too fast, only had five minutes
