Saber saw  This is the tool you will need the most! If you don't have one by it or borrow one. Get a few bi-metal blades for it as well. I got them from a WalMart super store for about 4 bucks. Drill  I used a Makita cordless drill, any drill will work! Get a full set of drill bits, new ones work best. Having shape new bits is always nice. Metal Shears  used to trim the stove pipe for the barrel connections. Hammers  You know what this is for, just have a few around. Files  These are good for smoothing out the rough metal edges on the barrel openings and the lid. Air Grinder  This tool is not required to build the BBQ, but nice to have. I used it, with a cutting wheel on it, to cut slits in the barrels. I then used the saber saw to make the cuts. Screw Drivers  Um should know how to use these, right? Sockets  You only need a few of these, 7/16 and 1/2. I guess wrenches would work also. Just that there are 10 bolts on each damper, lotta screw'in to do. Soft Tape  This is one tool, I got from my wife, that makes the barrel opening and lid lay out easier to do.
