Vogolzang  The first thing you need is the barrel conversion kit and the double adaptor kit. Both kits cost $124.00 total. Vogolzang  I also had to get two more damper collars $18.00 each = $36.00 Barrels  You should be able to get these at no cost, I did anyway. Angle Iron  This is the stuff they have in the rack at Home Depot. I got 4 pieces about $10.00 total. Wheels  3 inch hard rubber wheels, Home Depot about $5.00 each = $20.00. Cedar Shelf  Cedar 1x6x6 and I used it all, True Value Hardware. Somewhere around $4.00 Platform  This is just a 2x6x8 pressure treated piece from Home Depot $8.00 Hinges  I used 3 brass hinges, about $3.50 each = $10.50. Grills  Major cost here. I paid $19.00 each, about $40.00 total. Fire Bricks  I got these from True Value hardware cost was .90 each and I got 20, only used 17 of them to line the bottom barrel, $20.00. Temp Gauge  Got it at Home Depot for $20.00. Misc Screws & Hardware  Screws, nuts & bolts. I intend on painting Big Smokey. The paint is somewhere around $4.00 a can. I figure about 4 cans should do it. Total in this area should be $25.00. Total Cost  Well, we stayed under the $320.00 mark. You could probably cut some corners here and there, but these are real world prices. If you look at the cost of one of those "professional" jobs we saved about $1000.00 and you can say you built it yourself! Big Smokey is an Icon of smokers and will be the envy of your block, I hope.
