Hey man...call this guy. He's in my hometown, and fixed my prop a couple of times last year, and does great work. You can probably ship it to him, and he'll turn it around in less than a week. I know he can work miracles with alum. and stainless props, and can straighten and balance brass....you'll have to ask him if it has chunks out of it though if it does.....I've never taken one to him missing metal.
He does a lot of work for most of the marinas around Wylie, and Norman.
