OK ok, Bass, you should ask me first for things like this in our area. Industrial pipe and steel on rush. They have a big rem yard. You could come by my shop, i probably have some bits around to make it work. If you are trying to doit the way i think you are, your going to need 3/8 to 1/2 to make it last. I have a design that could work a bit better though. Let me know.
Mike
