Thanks guys.
Don it feels perfect. I was following that thread you started on balanced in the hand. I tried to tiller based on how it felt when exercising the bow.I didn't use a yard stick or graph paper behind it on the tree or any of the usual stuff after I got it bending. Mostly because I was scared to leave it hooked on the tree that long after the last one blew up. I did use a gizmo a few times at the end just in case.
I would like to be able to tiller one without a lot of crutches so to speak. I marked out what I thought was a flat spot with a white pencil and then checked with a gizmo to see how close I was. I done alright. Probably always use a gizmo as it will spot tiny flat spots I couldn't see. I would like to know I could tiller a decent bow in a pinch if I didn't have all the fancy modern gadgets. Kinda like Jim Davis, I like that fellow.
