Another follower from the defunct BBQs Galore forum. When they took down the forum they were also kind enough to remove all useful product information from their website as well - I guess it's to force us into the local store to talk with someone. Oh well.
In any case, I have the Dr. Dave plans, but the parts list just says "2x3 metal studs". What gauge? What length? I can't find these at any Home Depot, Lowes, or lumber yard in the area (San Jose, CA) but I did find a local building materials wholesale company today who will sell to me. They have a pretty big variety though so I want to know what to ask for.
In case anyone is interested, I think I have a relatively good idea of what I'm going to build - it will be a very simple rectangle shape. Here is a simple diagram. The first rectangle is the top-down view, the second is the view from the front. It will be 36" high, 32" deep, and 115" long.
The grill will be a BBQs Galore Turbo STS 4-burner, with the STS side burner as well. Both will be run on natural gas. On the left side, I'm making a 3-sided opening for a smoker (currently a Weber Smokey Mountain but in the future, probably a Backwoods Party upright smoker). I debated also building in a Big Green Egg, but my wife talked me out of it.
I'm still trying to decide if I should add some sort of serving counter on the left side - there's a bit of space left on the patio. I might do a circular type table, though I have to figure out how to bend Hardibacker. And still no real idea on the finish - maybe stone on the outside and a granite top. Will have to think about that one. I will take pictures and share as I go along here.
