I eventually want to build my own frame (don't we all) but I'd like to hone my brazing skills by making a few racks (or a lot of racks!) My question is this; what are you guys using if/when you make your own racks? What tubing, stainless, solid Al, etc? If you have any pictures that you'd like to share, please post them up. I have an idea in my head but I still have details to work out before attempting to build it.
