Woodfarmer- you want to remove as much compression wood in a tree before you release the tension wood. What this means is a wider face then you had. Gut the hinge from the face leaving tabs of Hinge on each side. In most trees you'll be cutting, 1/2" of hinge wood is sufficient and anything much thicker then that in ash with a narrow face will split the tree and or barber chair it. I put ash in the top three for most chair prone trees. White oak is second and hickory is first. Ash can be really manipulated well on the stump if you cut it up right. Swings great, holds great, but it can be a real ***** if you don't do it right.
