Some of you may have never heard of it but, there is a business called the Yard in Wichita. I stopped by there today with some friends to see if they had any aluminum about 3" in diameter. I was amazed at all the different sizes and shapes of aluminum they had. One piece I noticed was about 18" wide x 8" thick x 5' long. There was 12" diameter rod 10' long or more. If you do machine work at home or need it for your business, they have aluminum. They have a webpage also. I had been there years ago but, didn't remember seeing so much aluminum. No, I'm not part owner of the place.
