Thanks Gary, I did not consider the type of aluminum. I know it's not my thread, but I'm thanking you for sharing that knowledge. Now wouldn't that pipe have slot of copper and be problem to corrosion too.
So miter and a spool gun. That I got. Let's drink some beer and build this!!! Well it's not really a miter it's a chop saw that I change to a blade for aluminum. Do you got a miter Spence?
