pcluff,
I found that wood chips don’t last long enough for me. I have a pretty good supply of scrap hardwood boards around the shop and cut them about 6â€ÂX6â€ÂX1†or so thick. Just small enough to fit into the wood box. These pieces are dry and burn much as you describe. You don’t really want billowing smoke for the smoker. Just thin wisps of smoke that you can barely notice should last for a couple of hours or so. Look at the picture I posted in my first post and maybe you’ll get some idea of how much smoke mine is generating.
You should have a vent on top of the smoker, as well as on the side near the bottom. I’ve got mine “wide openâ€Â. Regulating the temperature takes a little time. Like ListerD says, once you get it where you want it it maintains that temperature pretty well. Small adjustments to the valve take some time to show up on the thermometer so you just have to be patient. I’ve read that you achieve the smoked taste in a relatively short time and that you don’t really need more than a couple hours smoke.
