First off, there are four, 1 inch vent holes 3 inches from the bottom of the drum each spaced evenly apart. In each vent hole is a 3/4 inch nipple (tight by the way, no air getting through) with a matching plug to control air flow.
The first level for the grate is about 4 inches from the top of the drum, held by 4 bolts drilled into the drum, then another grate is 6 inches lower held by another 4 bolts.
The vent stack I simply made by cutting a 2 inch hole on the top of the drum and attaching a 2 inch by 6 inch steel pipe to it, not much to explain there
The charcoal basket was a little difficult, having no wielding equipment. I bought a 10 inch charcoal grate then some expanded steel along with some 100 lb steel hanging wire, I wrapped the expanded steel around the grate the tied it all together and tight with the wire. Then to elevate the basket I got 3 inch bolts and some nuts and bolts to create "legs" for the basket
As a sort of personal why not I attached a dolly to the back to have an easy way to wheel it around where I wanted it to be.
Oh and here is the link to the pictures of the actual product: http://www.smokingmeatforums.com/gallery/album/view/id/96234/user_id/55519
Please Comment and give me as much design advice as possible, I'm also having a little trouble regulating the temperature on the lower 200-250 scale so any help on that would be appreciated as well.
Thanks Very Much
